## What it is
FreeOTP is an open-source two-factor authentication app for Android that generates one-time passwords using the HOTP and TOTP standards. Tokens can be added easily by scanning a QR code, and it works with any server implementing the open standards.

## Use cases
- generate two-factor authentication codes on android
- scan QR codes to add TOTP tokens
- replace proprietary authenticator apps with open-source alternative
- support HOTP and TOTP one-time passwords
- use 2FA with any standards-compliant server

## When to choose
- you need an open-source, standards-based 2FA app on Android
- you want to avoid proprietary authenticator apps
- you install apps via F-Droid or Google Play

## When to avoid
- you need encrypted cloud backup of tokens (consider Aegis)
- you need an iOS version
- you need desktop 2FA code generation
