When a profile has been verified, you have an extra indicator that the profile may indeed belong to a real person.
ID verification is one of the most robust ways to verify profiles. This is where a user uploads a photo of the passport or official ID optionally together with themselves. Often, an actual human will review this – although there are also some software solutions for this task – and confirm that the person is real. Most apps will add a badge icon with a tick, shield or similar to indicate that a user is verified.
Profile verification is one of the measures used to try and reduce scams and fake profiles and to increase the security of a dating app.
