Description

Impact

We are incorporating the password policies listed in https://github.com/vantage6/vantage6/issues/59. One measure is that we don't let the user know in case of wrong username/password combination if the username actually exists, to prevent that bots can guess usernames. However, if a wrong password is entered a number of times, the user account is blocked temporarily. This way you could still find out which usernames exist.
