If some user want to reset their password they could easily use the forgot password option from the login.
However, if this is not possible for some reason, you could also initiate a reset of the password by having Admin access to your team account.
Reset the user's password from Team Management
Go to the Settings page from the main menu.
Navigate to the Team tab.
Click on the Three Dots button near the required user
From the opened dropdown menu, choose Reset password
Done! You will see a confirmation that the new temporary password has been sent to the user's email.
Now the user can log under this password but this is strongly recommended to update the temporary password to a secure password of the user's choice.
