2FAS Pass Android
Source code for 2FAS Pass Android app
2FAS Pass Android is the open-source Android implementation of the 2FAS password-protected authenticator and secure vault project, which blends two-factor authentication (2FA) token generation with a secure vault for managing verification codes and potentially other sensitive credentials. While specific repo details vary by the community project, in the broader 2FAS ecosystem the Android clients are designed to generate TOTP (time-based one-time passwords) and HOTP codes for users’ accounts, helping them meet modern multi-factor authentication needs through a simple, private user interface that works offline and without needing an account. The app supports scanning QR codes to add new authentication tokens, allows local encrypted storage of secrets, and can restore tokens from backups or synced devices. 2FAS focuses on privacy and simplicity—tokens aren’t sent to third parties, metadata isn’t stored externally, and users can secure the app with biometrics or passcodes. -

PswGenDroid
Generates your passwords managed by PswGen on your mobile
PswGenDroid is the Android counterpart for PswGen. Based on the login information you entered with PswGen on your PC PswGenDroid re-generates your passwords depending on this data or shows a password you stored with PswGen. It's fully up to you how data (just a file) is synchronised or transferred to your mobile, therefore PswGenDroid doesn't need internet access or other rights but accessing your external storage, e.g. your SD card. PswGenDroid ist das Android-Gegenstück zu PswGen. Basierend auf den mit PswGen auf dem PC erfassten Daten erzeugt PswGenDroid die Passworte erneut auf dem Handy oder zeigt die von PswGen gespeicherten Passworte an. Es ist Ihnen völlig freigestellt, wie sie die Daten (nur eine Datei) synchronisieren oder auf das Handy kopieren, daher benötigt PswGenDroid keinen Internet-Zugriff oder andere Rechte, außer dem Zugriff auf den externen Speicher, wie z.B. die SD-Karte. -

zxcvbn
Low-budget password strength estimation
For over 30 years, password requirements and feedback have largely remained a product of LUDS: counts of lower- and uppercase letters, digits and symbols. LUDS remains ubiquitous despite being a conclusively burdensome and ineffective security practice. zxcvbn is an alternative password strength estimator that is small, fast, and crucially no harder than LUDS to adopt. Using leaked passwords, we compare its estimations to the best of four modern guessing attacks and show it to be accurate and conservative at low magnitudes, suitable for mitigating online attacks. We find 1.5 MB of compressed storage is sufficient to accurately estimate the best-known guessing attacks up to 105 guesses, or 104 and 103 guesses, respectively, given 245 kB and 29 kB. zxcvbn can be adopted with 4 lines of code and downloaded in seconds. It runs in milliseconds and works as-is on web, iOS and Android.
