Otpkey Authenticator

Otpkey Authenticator generates one-time passwords for two-factor authentication on iPhone, iPad, Mac and Apple Watch, and keeps them in sync through iCloud Keychain.

It works completely offline. No account, no server: your secrets stay in the system Keychain on your devices, protected by your passcode, Face ID or Touch ID.

Otpkey Authenticator works with every service that supports standard TOTP or HOTP codes, including Google, Microsoft, Amazon, GitHub, Facebook, X, Dropbox, Discord, PayPal, AWS, Synology and many more.

Switching from Google Authenticator? Scan its "Export accounts" QR code and all of your accounts are imported at once.
