Struggling to sign in a child account on a phone happens more often than you’d think. It pops up when a game freezes, a school app won’t open, or a simple check of homework suddenly shows a login error. The issue often comes from quick glitches, older apps, or setup steps that didn’t fully take.
Common culprits include outdated apps, location settings that are off, and software glitches on the device. Age restrictions or a wrong parental control setting can also block sign-ins. Knowing what to check helps you move fast without guessing.
This guide walks you through practical fixes you can finish in under ten minutes. Start with a quick restart on both phones, then update Family Link and Android to the latest version. If needed, verify location settings and clear the app cache on the child’s device.
If the sign-in still won’t cooperate, re-link the account or adjust supervision settings as described. Sometimes a simple toggle back and forth in the Family Link controls clears the block. In rare cases, you may need to pause supervision or, as a last resort, re-create the account with care.
Follow these steps now and you’ll likely get back to browsing, learning, and playing without delays. These tips come from current troubleshooting best practices and are designed to be easy to apply. If you run into stubborn blocks, a quick check on Wi Fi and a fresh attempt often solves the problem.
Quick First Steps to Fix the Sign-In Block
When a child account won’t sign in, you want fast, reliable steps that don’t require hours of troubleshooting. These quick actions focus on the most common causes, from app versions to device readiness. Follow these steps in order, and you’ll likely restore access without a lot of back-and-forth. Each sub-section below provides a concise, task-focused plan you can complete in minutes.
Update the Family Link App Right Away
Step-by-step: Open the Play Store on the child’s Android phone and search for Family Link. Look for both the child and parent versions and update both if available. Do the same on the parent phone. Updates fix bugs introduced by recent changes and ensure compatibility with current Android and app security requirements. If no update shows, check auto-update settings to confirm the apps can update in the background. After updating, test signing in on the child device. If the problem persists, recheck that both devices have internet access and that the latest versions are indeed installed. This quick check often resolves the issue in under ten minutes.
Restart Both Phones for a Fresh Start
A simple reboot can clear stuck connections and refreshing app states on both devices. Hold the power button on the child’s phone, then select restart or power off and turn it back on. Repeat on the parent device. The goal is to refresh network and app processes so sign-in requests flow cleanly. Give it a moment and then try signing in again. Pro tip: close all apps on both devices before the restart to speed up the process and reduce background activity that could interfere with the sign-in.
Verify Your Phone Runs the Right Android Version
Android version compatibility matters for Family Link and the sign-in flow. On the child device, go to Settings > About phone > Android version to verify the current build. If the version is below 5.0, update by going to Settings > System > System update and download over Wi-Fi. Restart after the update. Family Link uses the latest security features available in newer Android builds, so keeping the OS up to date helps ensure smooth sign-ins and proper supervision controls. If the device can’t update, consider whether it still meets minimum requirements and plan next steps accordingly.
Clear App Junk and Retry the Sign-In
When sign-in stalls on a child’s phone, a quick clean of the app’s temporary data can restore normal flow. Clearing cache removes stray files that can confuse the login process. It doesn’t touch your personal data, so you can retry with a fresh start. After clearing the cache, open Family Link again and attempt sign-in. If the problem persists, move on to an alternate method that leverages device settings. A simple, targeted reset often resolves most glitches without reinstalling anything.
How to Clear Cache on the Child’s Phone
Precise path: Settings > Apps > See all apps > Family Link > Storage & cache > Clear cache.
This action trims temporary files that may block sign-in while keeping your data intact. It’s quick and safe, and you can perform it in moments from any standard Android device. After clearing the cache, reopen the Family Link app and retry the sign-in. If the issue remains, double-check that the device has an active internet connection and that both devices are running the latest app versions. A cache reset solves most minor hiccups in a few taps.
Sign In Fresh Through Phone Settings
Alternative path: Child’s phone Settings > Google > Parental controls > Get started > Child or teen. Enter supervised account. Approve any prompts. This approach works if the app path fails. Ensure Family Link is updated on both devices before testing. If prompts appear for account verification, follow them carefully. After you complete the flow, try signing in again on the child’s device. If needed, re-link the account or adjust supervision settings as described in the guide. This can clear blocks without starting from scratch.
Check Parent Settings and Common Sign-In Errors
When your child can’t sign in, the issue often hides in the parent controls or a familiar glitch. This section helps you verify the most common blockers and fix them quickly. You’ll learn where to check approvals, how to spot account mismatches, and what to do when you see signs of supervision or account errors. If you follow these steps, you’ll likely restore normal access in a few minutes, keeping your family moving forward.

Approve Requests from the Parent Phone
In the Family Link app on the parent phone, you can control when and where your child signs in. Start by tapping your child’s profile, then go to Settings, and check notifications. If a sign-in attempt appears, approve it right away to allow a new device or session to connect. Make sure the child’s device is tied to your account correctly and that both devices have stable internet. If you don’t see a prompt, confirm the parent and child devices are logged into the right accounts.
This approval step protects your child while keeping sign-ins smooth. If you notice repeated prompts that don’t appear on the parent phone, verify you’re using the latest Family Link version on both devices and that the child’s account is the supervised one linked to your account. A quick recheck of device names under Signed-in devices can prevent future hiccups. By staying on top of approvals, you minimize interruptions during homework time or app usage.
Fix Wrong Account or Supervision Glitches
Sometimes the problem isn’t the device but how the account is supervised. First, confirm the child is using a supervised account exactly as configured in Family Link. If the sign-in error persists, you can temporarily remove supervision from the parent app and re-add it. This process often clears misfits between the child’s Google account and the supervision layer. Avoid creating a new account unless truly necessary, as re-linking is typically quicker and less disruptive.
Keep an eye out for specific symptoms that hint at what’s wrong. If the child’s device shows “sign-in blocked” after a password change, you likely need to re-authenticate the account within Family Link. If you see a mismatch between the child’s profile name and the account email, double-check the linked Google account in the parent app. After re-adding supervision, test sign-in again and monitor for any repeat warnings. In most cases this reset resolves the issue without requiring a full reinstall or a new account. If you must restructure, document steps and test after each change to avoid compounding issues.
Last Resort Fixes When Nothing Else Works
When you’ve exhausted the obvious fixes and the sign-in still won’t cooperate, it’s time to move to careful, high-impact steps. These adjustments are designed to resolve stubborn blocks without creating new problems. Treat them as the final set of options you try before considering a major rebuild of the account or device setup. You’ll approach each fix with a clear goal: restore a clean, reliable connection between the parent and child devices while preserving data and supervision rules.
Suspend and Rebuild Supervision
If the problem hides in the supervision layer, a controlled reset can clear the last lingering misconfiguration. Here’s a practical approach:
- On the parent phone, open Family Link and locate the child’s profile.
- Temporarily remove supervision by unlinking the child account, then re-add supervision and re-link the account.
- Complete any prompts for re-authentication and re-verify the child’s device association.
Why this helps: it rewrites the handshake between the Google account and the Family Link controls. It’s less disruptive than a full account recreation and often resolves mismatches that block sign-in.
Re-create the Supervised Account (With Caution)
If re-linking doesn’t fix the issue, you may need to re-create the supervised account on the child’s device. This is a more involved step, so plan for a brief downtime and communicate with the child about the change.
- Back up critical data from the child’s apps if possible.
- In Family Link, remove the existing supervised profile from the parent device.
- On the child device, sign out of the Google account and remove the device from the account if prompted.
- Re-create the supervised profile from the parent device and walk through the setup steps again.
- Re-link the child’s Google account and restore any essential app data.
This method resets the sign-in flow and often clears stubborn blocks caused by mismatched identifiers. It’s a last resort, but it avoids a full factory reset when you proceed carefully.
Factory Reset the Child Device (Last Resort)
If every other option fails, a factory reset can be the cleanest way to start over. It erases all apps and data, so treat this as a final option.
- Before you reset, back up photos, documents, and any needed app data.
- On the child device, go to Settings > System > Reset > Factory data reset.
- After the device restarts, set it up as a new device and re-install Family Link.
- Link the child account to Family Link during setup and test sign-in.
Why it’s last resort: you lose all local data and app settings. It eliminates software glitches that individual app reinstalls can’t fix. If you can avoid it, try the lighter fixes first.
Check for System-Wide Issues and Known Outages
Sometimes the barrier to sign-in isn’t on your devices at all. A temporary service disruption or a global change in Google accounts can affect supervised sign-ins.
- Visit status pages or trusted community forums to see if others report similar issues.
- If an outage is confirmed, plan a brief pause and retry after a few hours.
What to do in the meantime: keep devices updated, confirm both ends have internet access, and avoid multiple sign-in attempts that could trip security protections.
Verify Time, Date and Regional Settings
Mismatched time settings can cause authentication problems that look like sign-in blocks.
- On both devices, ensure automatic date and time are enabled.
- Confirm the region/language settings match your account region when possible.
- If you recently traveled or changed time zones, re-check these settings and retry sign-in.
This is a simple sanity check that often resolves oddly persistent blocks without touching accounts or apps.
Clear All Data for Family Link and Reinstall
If clearing the cache helped but the problem returns, a deeper data reset can stop a stubborn loop.
- On the child device, go to Settings > Apps > Family Link and choose Clear data (not just Clear cache).
- Do the same for any related Family Link components on the parent device.
- Reinstall Family Link from the Play Store on the child device and sign in again.
- Re-link the account and test the sign-in flow.
This step removes any corrupted data fragments that basic cache clears miss. It’s safe if you have a recent backup plan and you proceed methodically.
Disable Non Essential Accessibility or Security Features Temporarily
Some features can interfere with sign-in flows. Disable them temporarily to test if they’re the culprits.
- Accessibility features: Settings > Accessibility, turn off any tools that could affect input or prompts.
- Any third party security apps or VPNs: disable briefly to ensure they aren’t blocking authentication.
- Secure folders or device guards: temporarily disable and test the sign-in again.
If sign-in works with these features off, re-enable them one by one to identify the exact conflict.
Clean Re-authentication Path on the Parent Device
A clean re-authentication path helps ensure the parent account is fully aligned with the child’s session.
- Open Family Link on the parent device.
- Navigate to the child’s profile and remove any stale device associations.
- Add the child’s device again and confirm the correct parent account is chosen during the flow.
- Complete all prompts, then retry the child sign-in.
A fresh authorization flow can clear subtle permission or session issues that linger after earlier fixes.
Document and Re-test in Stages
When you run through these last resort fixes, do it in stages and test after each step.
- Stage 1: Rebuild supervision without data loss (relink or toggle supervision off and on).
- Stage 2: If still blocked, recreate or reset with smart backups.
- Stage 3: If needed, perform a full reset only after testing every lighter option.
Keeping notes helps you avoid repeating steps and makes it easier to explain what you tried if you need to contact support.
When to Seek Official Support
If the problem remains after all these steps, contact Google Support or your device manufacturer’s support team. Have ready:
- The model and Android version of both devices.
- Screenshots of any error messages.
- The exact sequence of steps you tried.
- Confirmation that you followed supervision and account linking steps correctly.
Getting expert help early can save hours of frustration and prevent accidental data loss.
If you follow these last resort fixes in a calm, methodical way, you’re very likely to restore reliable sign-ins. The goal is to reestablish a clean, predictable flow between the parent and child accounts while preserving safety controls. Remember, a careful approach beats random clicking every time.
Conclusion
Fixing a child account sign in on a phone usually comes down to a few quick checks and smart resets. Start with updates on both Family Link apps, then restart both smartphones to refresh the connections. Clearing the child’s app cache, verifying location and account settings, and confirming the parent’s approvals cover the most common blockers in minutes.
If the sign in still stalls, re-link the supervised profile or temporarily toggle supervision as described. A clean re-authentication path on the parent device often resolves stubborn misalignments without starting over. For the rare cases that require deeper work, a data aware approach—backing up essential data, then re‑creating the supervised profile—can save time and avoid a factory reset.
Ongoing prevention matters as well. Keep all apps updated, schedule regular restarts, and avoid letting third party security tools interfere with authentication. Enable automatic updates where possible and check time, date, and regional settings to prevent future blocks. By sticking to these routines, you reduce the chance of repeated issues and keep your smartphone family connected and productive.
