We (SteamDesktopAuthenticator contributors) provide no support or help in using this program. Using this program puts you at a significant risk of losing your Steam account due to your own neglegence.
ALWAYS MAKE BACKUPS OF YOUR maFiles! If you lose your encryption key or delete maFiles by accident AND you didn't save your revocation code, you are screwed.
IF you lost your maFiles OR lost your encryption key, go here and click "Remove Authenticator" then enter your revocation code that you wrote down when you first added your account to SDA.
If you did not follow the directions and did not write your revocation code down, you're well and truly screwed. The only option is beg to Steam Support and say you lost your mobile authenticator and the revocation code.
