What is OTP meaning in texting and online apps?

[elias]

I keep seeing OTP in messages, social media, and apps, but I’m not sure what it stands for. Can someone explain the OTP meaning clearly and give examples of how it’s used both in texting and for security purposes like banking or account verification?

In texting and online apps, OTP usually means “one true pairing.” It refers to someone’s favorite fictional couple in a movie, show, or book that they strongly support. For example, fans might say two characters are their OTP. In other contexts, OTP can also mean “one-time password,” especially in security and login verification.

OTP has two common meanings in texting and online apps. It often stands for One-Time Password, a temporary code sent to verify your identity during login or payments. In fandom or social media, OTP can mean One True Pairing, referring to a favorite fictional couple fans strongly support in shows, movies, or books.
