Native authenticator · iPhone & Mac

Your codes. Your devices.
Nobody else’s servers.

OTPski generates time-based and counter-based codes on iPhone and Mac. Secrets are sealed on device, the vault key lives in iCloud Keychain, and the two apps share one vault — with no account to create and no OTPski cloud to trust.

Both apps share the same vault through your iCloud.
