Secure 2FA code client of 2FAuth server that works offline
About this app
Pocket2FA is a mobile companion for the 2FAuth self-hosted two-factor authentication web application. It generates TOTP and Steam codes locally on your device while synchronizing with your own 2FAuth server.
Features
• Generates TOTP and Steam OTP codes locally — secrets never leave your device
• Encrypted storage using platform security (Android Keystore)
• Optional biometric authentication (fingerprint / face recognition)
• Real-time code refresh with countdown timer
• Privacy mode: hide codes by default, reveal with long-press
• One-tap copy to clipboard
• Group organisation for easy browsing
• Service icon support
• QR code scanning (camera or gallery image)
• Multiple 2FAuth server support
Requirements
A self-hosted instance of 2FAuth is required. This app does not work as a standalone 2FA manager — it is a native client that extends 2FAuth.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be net.gmartin.pocket2fa is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 0.9.16 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Pocket2FA first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Pocket2FA, and a listing is removed when the evidence for it stops holding up.

Permissions Required
What each permission lets Pocket2FA do. A highlighted one is worth a second look — not necessarily wrong, just worth asking whether this app needs it.
Previous Versions
The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
