About this app
2FAS Auth makes the 6-digit codes that many sites now ask for after your password. Scan the QR code a site shows you once, and from then on the app produces a fresh code every 30 seconds. It works with anything that follows the usual TOTP or HOTP standard, which covers Google, Microsoft, Dropbox and most of the rest.
There is a backup option so a lost or replaced phone does not lock you out of all your accounts at once, and the app pairs with the 2FAS browser extension for signing in on a computer. Setup is a scan and a tap.
One note: the icons and artwork in the app are not part of the open source project and carry their own licence. The code itself is GPL.
