To use Between on your PC, you have to go through a 2-step process of logging in.

If you received this notification during your login attempt, it means you were successful with step 1 but failed step 2.

The reason for your failed attempt at step 2 is because network administrators at secure establishments such as banks, government offices, public organizations, and certain companies tend to block the use of messenger programs due to security reasons.

You won’t be able to use Between for PC in these types of environments.
