About this app

AVA is an unofficial, open-source Steam Guard authenticator. It is a community
project and is not affiliated with Valve or Steam in any way.

Your authenticator lives on your device, encrypted. AVA is built for people who
want their Steam two-factor codes and trade confirmations in one place they
control.

WHAT IT DOES

• Steam Guard codes — a live list with countdown rings and tap-to-copy.
• Trade confirmations — approve or decline trades and market listings, in
batches, without an embedded browser.
• Trade offers — received, sent and history, with both sides' items shown, and
gift / one-sided / escrow warnings before you accept.
• Sign-in approval — approve Steam logins from inside AVA, with the device and
location shown, just like the official app.
• Inventory and Community Market — browse your inventory and list items with
live Steam fees and price history.
• Redeem Steam keys — activate a product key on any account you hold.
• Device management — see every device signed into your account and sign any of
them out remotely.
• Steam Family groups — invites with pre-join checks, and a group overview.

MIGRATION

AVA reads and writes the classic .maFile format (PBKDF2/SHA1 + AES-256-CBC), so
authenticators from Steam Desktop Authenticator and similar tools move over
unchanged. Exports from Steam++ / Watt Toolkit are imported too. You can export
your .maFile at any time — your data is never locked in.

SECURITY

• A 6-digit PIN guards a random 256-bit key held in your device's hardware
keystore; local storage is encrypted with AES-256-GCM.
• Fingerprint or device-PIN unlock.
• Every irreversible action — accepting a trade, joining a family group — takes
a deliberate press-and-hold, not a stray tap.
• Codes work offline. Fonts and assets are bundled; nothing is downloaded at
runtime.

AVA Pro (optional) unlocks the Neon and Pixel skins and removes ads. The free
version shows ads on Google Play. Everything to do with your Steam account works
the same either way.

The first-run privacy notice was wrong. It said AVA has no backend of its own and connects only to Valve. In fact Pro entitlement checks and feedback reach the developer's own services, and the free tier shows ads. Nothing the app does has changed — only the description of it. If you agreed to the old wording, AVA asks once more.
