Two-factor authentication (2FA)

Enabling 2FA

1. Sign in to your SheetForge account
2. Go to Profile > Two-factor authentication
3. Scan the QR code with an authenticator app (Google Authenticator, Authy, etc.)
4. Enter the 6-digit code to confirm setup

Logging in with 2FA

After enabling 2FA, you will be asked for a 6-digit code from your authenticator app each time you sign in.

Recovery

If you lose access to your authenticator app, use the recovery link on the 2FA challenge page. A recovery code will be emailed to your registered email address.

Admin accounts

2FA is mandatory for admin-level accounts and cannot be disabled.
