Because of AI Robot bad actors putting malware on web sites, the Captcha puzzles are to prove you are a Human, Bots have a hard time getting past the Captcha.
You may also sign up for 2FA to have the site send a numerical code to your smartphone or Authenticator app when you login to prove it is you.
Many financial and health sites do this now.
