OTP.
- RFC 6238 Time-Based One-Time Password Algorithm
- RFC 4226 HMAC-Based One-Time Password Algorithm
- Generate random base32 secret by RAND_bytes, or
- Use existing secret, base32 or plain text (internally converted to base32)
- Specify
X(unix timestamp),T0(start time) or compute based on current time - Specify hash algorithm
- Generate [key URI](Key Uri Format](https://github.com/google/google-authenticator/wiki/Key-Uri-Format)
- Generate QRCODE in .png or .svg format
