Save your 2FA backup codes
Last updated Oct 5, 2026
When you turn on two-factor authentication, you get 10 single-use backup codes, shown once — store them offline.
Backup codes let you back in — or turn off 2FA — if you lose access to your authenticator. You get 10, and each code works once.
- On the backup codes screen shown during 2FA setup, select Copy all (or write the codes down).
- Store them somewhere safe and offline, separate from your phone.
- Select I've saved these to finish.
Important
The codes are shown only once. If you lose both your authenticator and your backup codes, you may be locked out — set up a recovery key as a further safety net. For a fresh set, open Settings, then 2FA, and select Create new codes under Backup codes (the old set stops working).
