2FA: Two-Factor Authentication2FA Two-Factor Authentication is a type of multi-factor authentication. It is a method of confirming users’ claimed identities by using a combination of two different factors: 1) something they know, 2) something they have, or 3) something they are. A third-party authenticator (TPA) app enables two-factor authentication, usually by showing a randomly-generated and constantly refreshing code which the user can use. is a type of multi-factor authentication2FA Two-Factor Authentication is a type of multi-factor authentication.

Beta: BetaBeta Beta is the software development phase following alpha. A Beta phase generally begins when the software is feature complete but likely to contain a number of known or unknown bugs. Software in the beta phase will generally have many more bugs in it than completed software, speed or performance issues, and may still cause crashes or data loss. The focus of beta testing is reducing impacts to users, often incorporating usability testing. is the software development phase following alphaAlpha The alpha phase of the release life cycle is the first phase of software testing..
