AVA: Steam Guard Authenticator

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.
