Origin, History & First Known Use of OTP
The slang OTP (One True Pairing) first became popular in the early 2000s within online fandoms, especially communities centered around TV shows, anime, and movie characters. Fans on forums such as LiveJournal, Tumblr, and fanfiction websites used OTP to declare their passion for a particular pairing.
The phrase “One True Pairing” reflects the idea that out of all possible relationships, this one is your ultimate favorite. Over time, the term spread beyond fandom culture and into everyday texting.
The technical meaning of OTP (One-Time Password) emerged separately through cybersecurity and digital banking. As online services grew, OTPs became essential for two-factor authentication (2FA) and safe login verification.
By the 2010s, both meanings had become widely recognized, making OTP a versatile but context-dependent abbreviation.
How People Use OTP in Daily Conversations
In casual texting, friends use OTP mostly to talk about couples they love or enjoy watching together. It doesn’t have to refer to fictional characters—real-life couples can be referred to as someone’s OTP too.
Examples of everyday use:
- Talking about celebrity couples
- Discussing favorite TV show romances
- Commenting on TikTok relationship videos
- Sharing opinions in group chats
People may also use OTP to talk about themselves humorously:
- “My coffee and I are the real OTP.”
- “Pizza + me = OTP forever.”
Outside of fandom or romance, “OTP” is used for mundane purposes like telling someone you’re on the phone or sharing a one-time password during login.

Because OTP has multiple meanings, people often misinterpret it. Common mistakes include:
- Thinking “OTP” always refers to verification codes
- Misreading “OTP” as “on the way” (which is actually OTW)
