OTP can refer to several technologies. One Time Password (OTP) is a password that is valid for only one login session or transaction, used to enhance security. It is commonly used for two-factor authentication (2FA) or multi-factor authentication (MFA), providing an extra layer of security beyond username and password. Another meaning of OTP is Erlang's Open Telecom Platform, a set of libraries, tools and design principles used in the Erlang programming language for building robust, scalable, and fault-tolerant systems.
