Steam Authenticator

An unofficial, fully maFile-compatible Steam Mobile Authenticator for Android.

✨ Features 🔑 Steam Guard codes — 5-character codes with a live 30-second timer, multiple accounts. 📂 Full maFile compatibility — import/export .maFile (plain and SDA-encrypted with manifest.json). Files are interchangeable with the desktop SDA. ✅ Trade & market confirmations — accept / decline / accept-all, with auto-refresh, item images and a trade-details view. Pull-to-refresh. 📱 QR sign-in — scan the QR on Steam's PC login page to approve the login from your phone. 🔗 Link a new authenticator — full enrollment flow (login → AddAuthenticator → SMS finalize), with revocation code. 🧹 Remove Guard — unlink the authenticator from the account via revocation code. 🔄 Session refresh — renews access tokens via the refresh token; full Steam sign-in when needed. 🔒 Security — maFiles are always encrypted at rest (AES-256) with a key kept in the Android hardware Keystore; optional app lock via fingerprint / device PIN. 🌍 8 languages — English, Русский, Deutsch, Français, Español, Português (BR), 中文 (简体), Türkçe. Follows the system language, with an in-app override.
