How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
This is a two-factor authentication library and open-source multi-factor authentication implementation. It provides a suite of tools for implementing security workflows that require a second layer of verification beyond standard credentials. The project implements both time-based one-time passwords and HMAC-based one-time passwords. It includes utilities for generating these codes based on shared secrets and counters, following industry standards such as RFC 6238. The library covers cryptographic primitives including Base32 secret key encoding, dynamic truncation extraction, and symmetric ke
This project is an Android password manager application that provides an end-to-end encrypted vault for storing and synchronizing login credentials, secure notes, and identities. It functions as a secure storage system using zero-knowledge encryption to ensure that only the user can decrypt their stored data. The application integrates directly with the Android system to provide an autofill service that populates usernames and passwords into mobile apps and browser login fields. It also serves as a passkey management wallet for FIDO2 cryptographic passkeys and a time-based one-time password a
This project provides a complete OpenVPN server deployment packaged as a Docker container, with an integrated EasyRSA certificate authority for automated public-key infrastructure management. It handles the full lifecycle of a VPN server, from initial PKI bootstrap and server configuration generation to client certificate issuance and revocation, all within a containerized environment. The server is configured entirely through Docker environment variables, eliminating the need for manual configuration file editing. It supports time-based one-time password (TOTP) authentication as a second fac
2FAuth is a self-hosted two-factor authentication server and credential vault. It functions as a web-based authenticator app used to organize and generate time-based one-time passwords and other security codes for multiple accounts in a central location. The system distinguishes itself as an API-driven security manager, allowing authentication codes to be integrated into automated workflows and external applications. It also supports shared security credentialing through the use of isolated vaults and shared folders for team collaboration. The project covers a broad range of security and dat
This project is a Pluggable Authentication Module for Linux systems that enforces multi-factor identity verification. It integrates directly into the system authentication stack to require time-based one-time passwords alongside standard user credentials, providing a mechanism to secure local and remote shell access.
The main features of google/google-authenticator-libpam are: PAM Modules, TOTP Authentication Systems, Pluggable Authentication Backends, Credential Verification, One-Time Passwords, Two-Factor Authentication, Clock-Abstracted Time Validation, Clock Skew Tolerances.
