How are passwords stored in Instagram posting services?

Question

Instagram

There are services for auto-posting likes, etc., vinste.ru https://parasitelab.com , etc., they require a password for Instagram to work, so they store user passwords in the database, or do they work somehow through a token? When you change your password on Instagram, you immediately need to enter a new password.

Answer 1

In clear text
If they are hacked, then all passwords will leak into plain text

Answer 2

If some service asks for a password from Instagram, then something is wrong with this service, in any case permission and tokens. Otherwise - what could be otherwise? Give password xD

Answer 3

Most often they store it in their database, of course, it’s smart to log in and only store the token, but in general, you give your password to us, it doesn’t matter how they store it in the end
