Stratum - Authenticator App

Stratum is a mobile application that provides an extra layer of security to your online accounts by implementing 2 Factor Authentication. This means that in addition to your username and password, you will also need a one-time code provided by Stratum to log in. This ensures that even if your login details are compromised, your account remains safe.

The app supports both TOTP (Time Based) and HOTP (Counter Based) authenticators, using popular hashing algorithms such as SHA1, SHA256, and SHA512. It also supports various providers such as Mobile-Otp (mOTP), Steam, and Yandex.

One of the key features of Stratum is its compatibility with most providers and accounts. It also allows for easy migration of accounts from other supported apps. Additionally, the app offers a backup and restore feature, allowing you to save your authenticators with strong encryption. This means that in case you lose or change your phone, you can still access your accounts.

Stratum has a sleek and modern design, with the option to choose between light and dark themes. It also uses recognizable brand logos and icons for each code, making it easy to find your authenticators. The app also allows for customization, such as setting icons and renaming authenticators, as well as organizing them into categories.

Security is a top priority for Stratum, which is why it offers the option to set a password and use biometric authentication to protect your codes. The app also requires minimal permissions and does not need internet access to function. It even has a Wear OS feature, allowing you to view your authenticators directly from your watch. However, please note that a connection to your Android device is required for this feature. It is also important to mention that the F-Droid distribution of the app is not compatible with Wear OS due to non-free dependencies.
