Using 2FA Backup Codes

Using 2FA Backup Codes

Backup codes are your safety net when you can't access your authenticator app.

What They Are

A set of one-time-use codes generated when you enable 2FA. Each code works once, then is consumed.

When to Use Them

• You lost or replaced your phone
• Your authenticator app was deleted or reset
• You're temporarily without your usual device

How to Use

1. At the 2FA prompt, click Use a backup code
2. Enter one unused code
3. You're signed in — that code is now spent

Regenerating Codes

If you run low or suspect your codes leaked:

1. Go to Settings → Security → Backup Codes
2. Click Regenerate
3. The old set is invalidated immediately; save the new set

Storage Tips

• Save them in a password manager, not in plain text on your desktop
• Print a copy and keep it somewhere physically secure
• Never share backup codes — anyone with them can bypass 2FA
