 GOTP is a Golang package for generating and verifying one-time
 passwords. It can be used to implement two-factor (2FA) or multi-factor
 (MFA) authentication methods in anywhere that requires users to log in.
 .
 Open MFA standards are defined in RFC 4226 (HOTP: An HMAC-Based One-Time
 Password Algorithm) and in RFC 6238 (TOTP: Time-Based One-Time Password
 Algorithm). GOTP implements server-side support for both of these
 standards.
