## What is MustAuth?

MustAuth is a Two-factor authentication application to secure personal account.  It  implements two main open standards: HOTP and TOTP, which means no proprietary server-side component is necessary.
MustAuth is extremely easy to use. Tokens can be added easily by scanning a QR code from camera or photo album. Besides, other applications can add tokens into MustAuth through `otpauth` and `mustauth` schema URL.
