OTPs are good!\nOTPs are a great way to protect your data from phishing and social engineering.\n\nBut what if you want to protect with a 2FA a mobile app?\nDo you see yourself the roundtrip? So MicroOTP comes in handy.\n\nAlso, how precious is the data you are going to access?\nSometimes you need a place safe than a smartphone to store your One Time Passwords.\nGoogle Authenticator is a great tool, but if you really go in paranoid mode, the smartphone is itself insecure.\n\nProject aim is to provide a banking grade security, long-lasting, OTP generators, that easy fit in your pocket,\nwith schematics and everything you need to build it by yourself.\n\nIt comes with a client-side only implementation of RFC 4226 (HOTP: An HMAC-Based One-Time Password Algorithm)\nand RFC 6238 (TOTP: Time-Based One-Time Password Algorithm).\n\nQuick features overview\n-----------------------\n\n- Generate OTP tokens as Google Authenticator App and others would do\n- Compliant with SSH, Bitcoin exchanges, Google Apps, etc.\n- Handle multiple secrets and multiple tokens generation\n- Always ready, OTP in \u003c1s\n\nHardware\n--------\n\n- Ai-Thinker ESP12\n- SSD1306 I2C 128x64\n- DS3231 RTC\n\nBuild requirements\n------------------\n- ESP12 with Micropython v1.8.7\n- adafruit-ampy\n- mpy-cross v1.8.7\n\nGoals\n-----\n\n- Support Apps (Mobile, Desktop, Browsers)\n- Schematics\n- STL Files\n- Pocket sizing\n\n\n\n![microotp breadboard](https://github.com/gdassori/microotp/raw/master/docs/img/microotp-breadboard.jpg)","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgdassori%2Fmicrootp","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgdassori%2Fmicrootp","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgdassori%2Fmicrootp/lists"}
