Authenticator App - FastOTP

1. Download and open the app, then create a passcode and enable Face ID or fingerprint lock for security. 2. Add your first account: choose Authenticator or 2FA on the website you’re securing, then scan the QR code or paste the setup key. 3. Confirm linking by entering the 6-digit code shown in the app back on the website or service. 4. Use codes to sign in: open the app, tap the account to copy the current code, and paste it during login. Enable autofill if supported by your device. 5. Organize and protect: rename accounts, group or sort them, and optionally turn on encrypted backup and multi-device sync so you can recover your tokens when you switch phones.
