What Authy is

Authy is a mobile two-factor authentication app for Android and iOS. It generates time-based one-time password (TOTP) codes and includes encrypted cloud backup and support for using the account across multiple devices. Those features give users a way to access authentication codes on supported phones and keep an encrypted backup of their setup. Authy’s Free plan costs nothing and includes two-factor authentication, encrypted cloud backup, and multi-device support. Its listed platforms are Android and iOS. The product’s listed code type is TOTP, so its core role is generating those codes for two-factor authentication. Encrypted backup and device synchronization are part of the feature set alongside code generation, making it suited to people who use more than one supported mobile device or want a backed-up authenticator setup. Authy’s listed details center on these mobile platforms, TOTP codes, encrypted cloud backup, and multi-device support.
