MyTOTP is a simple Go client for the Time-Based One Time Password (TOTP) protocol.

Works just like Google Authenticator for your Mac/Windows/Linux desktop.

Warning: this software is still in development and probably not ready to trust with your most sensitive credentials.

##Quickstart

1. Import a TOTP secret with a QR code or secret string.
   1a. Save the QR code to a local file, then run mytotp qr <filename> ; rm <filename>
   OR
   1b. Find the "secret string", then run mytotp add <name> <secret>
   You might have to click on "manual entry" in AWS or Google to see this string.
2. Run mtotp -w to see your code.
3. Secrets are stored encrypted in ~/.totp -- don't forget your passphrase!

##Usage

mytotp: TOTP client for the command line

Usage:
  mytotp [options]
  mytotp add <name> <secret>
  mytotp qr <filename>
  mytotp dump
  mytotp import <filename>
  mytotp -h --help
  mytotp --version

Options:
  -s, --secrets <file>        TOTP secrets file - KEEP PRIVATE [default: ~/.totp]. 
  -c, --continuous            Print codes continuously.
  -w, --web                   Run a simple web interface.
  -l, --listen <ip:port>      Local IP and port for web interface [default: localhost:8000].
  -h, --help                  Show this screen.
  --version                   Show version.

Optionally set the MYTOTP_PASSPHRASE environment variable to avoid the initial passphrase prompt.

DANGER: Running this tool on the same workstation you login from probably violates NIST-800-63 best-practices for two-factor. Similarly, using the mytotp dump feature puts your secrets at risk of compromise.
