Symptoms
- 'Couldn't sign you in' error message
- Password rejected repeatedly despite being correct
- Stuck on the sign-in screen loading spinner
- Account shows as 'not available' on this device
Likely causes
- CommonNo internet connection during sign-inChromeOS often needs to verify credentials online, especially the first sign-in after a password change.
- CommonPassword was recently changed on another deviceThe Chromebook needs the current password, not a cached older one.
- PossibleAccount removed or restricted by a school/work administratorManaged accounts can lose access if the organization changes policy or removes the user.
- PossibleCorrupted local user profile on the deviceA damaged profile can prevent login even with the correct password.
What to do
- Confirm the Chromebook is connected to Wi-Fi before attempting to sign in again.
- Double-check the password by testing it at accounts.google.com from another device first.
- If the password was recently changed, use the new password rather than an old saved one.
- Try removing and re-adding the account from the sign-in screen (click the account, then 'Remove this user').
- If this is a school or work account, contact the administrator to confirm the account is still active and accessible.
- As a last resort, powerwash the device if the local profile seems corrupted and the account works fine on other devices.
When to call a pro
For managed school/work accounts, the organization's IT administrator is the right contact, not a repair shop.
