About this app

Yandex.Key is an authenticator generating one-time passwords (OTP) for Yandex, Google, GitHub, Dropbox, Vk.com, and other services with two-factor authentication (2FA). To log in to Yandex, enter this one-time password instead of your regular password, and to sign in to other services, with your normal password.

— Data protection
Yandex.Key safeguards your account from being hacked and your personal information from being stolen. One-time passwords will be available only to you, on your mobile device.

— Security standards
Yandex.Key supports two-factor authentication (or two-step verification) on all services using RFC 6238 and RFC 4226, except for services which only use sms.

— Backing up
Back up the data in Yandex.Key on Yandex's servers, to use in case something happens to your device. It's secure: you backup is encrypted using a password that only you know.
