OTP

Single-use security number

OTP is an initialism with two common meanings in different contexts.

In internet and fandom slang, it stands for "one true pairing"—the romantic couple, often fictional, that someone considers the ideal match: My OTP is finally canon!

In security and banking, OTP means "one-time password," a temporary code used for authentication that expires after a single use or short time period: Enter the OTP sent to your phone.
