Time Drift Correction

You and the service share a secret key that never leaves your device

Codes change every 30 seconds based on current UNIX timestamp

Uses HMAC-SHA1 to generate codes that are cryptographically secure

Backup your secret keys: Store them in a password manager in case you lose access
Use different secrets for each service: Never reuse 2FA secrets across accounts
Enable backup codes: Most services provide emergency one-time codes
Keep your device time synchronized: TOTP requires accurate time to work correctly
