Release Notes of Invantive® Authenticator 24.1.3-BETA

Invantive® Authenticator

Invantive Authenticator generates TOTP PIN-codes, based upon Invantive Keychain for use with Exact Online, Amazon Web Services, etc. The Authenticator also contains a high-performance reverse search of the generation time of a known PIN-code according to RFC 6238 across all registered TOTP-accounts. For optimal security, accounts can also be obfuscated by replacing all context by random pictures and names.

The release number consists of three elements: major version, minor version and patch version. The latest version is listed on top of the list, with older releases further down.
