Forgot your password? Reset it
If you forget your password, you get a link by email to set a new one. The link works only once and expires quickly. Once you've reset it, every device signed in to this account is signed out.

Steps
- On the sign-in page, click “Forgot password?”.
- Enter your “Email address”, then click “Send reset link”.
- The screen shows “Request received”. Bút Nghiên always shows this message so it doesn't reveal which emails have an account; if your email has an account, the email arrives within a few minutes.
- Open the email (check the spam folder too) and click the link. The “Reset password” page opens.
- Enter a “New password” (at least 8 characters) and “Confirm new password”, then click “Reset password”.
- When you see “Password reset”, click “Go to sign in” and sign in with your new password.
Common errors and how to fix them
- “The password reset link is invalid or has expired. Please request a new link.” → click “Request a new link” and start over.
- “Passwords don't match.” → type the same password in both boxes.
- “The new password must be at least 8 characters.” → choose a longer password.
- “Couldn't reset the password. Please try again.” → check your internet connection, then click again.
- Each link works only once. If you clicked send several times, use the link in the most recent email.
- If your teacher created your account (by importing a student list): you get an invitation email, and the link opens the “Activate account” page. Set a password (at least 8 characters) and click “Activate account”; when you see “Account activated”, sign in with your email and the password you just created. The invitation link is valid for 7 days.
- If the invitation link has expired or the email never arrived: use “Forgot password?” with that same email to get a new link. Don't sign up again with the email your teacher already used.
