OTPmanager: One-Time Password Manager
OTPmanager is an open-source one-time password manager that allows users to store, generate, and manage one-time passcodes for multi-factor authentication across various online accounts and services. It features a simple and user-friendly interface.
What is OTPmanager?
OTPmanager is an open-source, self-hosted one-time password manager application that allows users to conveniently store, generate, and manage one-time passcodes (OTPs) for multi-factor authentication across their various online accounts and services that support two-factor authentication.
It provides a simple and intuitive user interface to securely store OTP secrets, which are encrypted before being saved to the database. Users can easily generate valid one-time codes for each service by simply clicking on the service name. OTPmanager automatically tracks usage and refresh times for each OTP.
Some key features include:
- Open-source code and available free of cost under GPLv3 license
- Self-hosted option for better privacy and control over data
- Secure encrypted storage of OTP secrets
- Supports common OTP standards like HMAC-based OTP and Time-based OTP
- Automatic sync across devices with end-to-end encryption
- Cloud backup support
- Customizable themes
- Available as web-based app, Android & iOS mobile apps, and browser extension
By using OTPmanager instead of proprietary authenticator apps, users can have full control and ownership of their own OTP secrets rather than trusting third-party services. As it is open-source, its security standards can also be publicly vetted. The app focuses specifically on OTP management only which aligns well with the UNIX philosophy.
