SecKey

SecKey provides one time passwords to be used with the two factor authentication of Dropbox, Google, Facebook, GitHub, Proton Mail and many more.

It adds a second layer of security for your online accounts. This works by generating one-time passwords on your mobile devices which can be used in conjunction with your normal password to make your login nearly impossible to hack.

Securely stored in the keychain of your device. When iCloud Keychain is on, all your One Time Passwords are synced to your other devices.

The app does not collect information about you. You won’t be asked to allow access to your contacts or your location.
