OTP

1. One-time password. Used to clarify and confirm if you are the registered person by sending you a message(most probably by SMS) with a password(can be numerical, alphabetical or both).

2. One True Pairing. A name given to your most favourite romantic pairing, whether fictional or real(although, I prefer you pair fictional characters than pair real people)

1. "Hey Carl, could you check your phone? I've sent you an OTP"

"Sure, do you want me to read it out for you or do you wanna read?"

2. "Stephanie, what's your OTP?"

"I don't have a particular one, but I have to choose, Ron x Hermione would be great.

OTP

One True Pairing. Usually in fandom where you think two characters would likely to be a great couple and are made for each other, like soulmates

Example:
Person 1: Oh my god Draco and Harry are so OTP
Person 2: I know right, they are born to be with each other
