  The following combinations are tried in order:

  1: If one is provided, the suggested username
  2. The first part of the email address (everything before the @)
  3. If both firstname and lastname is provided, "F.L".
    F is x number of letters from firstname, where x starts at 1 and goes up to the full length of firstname.
    L is lastname.
  4. If firstname is provided without lastname, firstname only.
  5. If lastname is provided without firstname, lastname only.
  6. If both firstname and lastname is provided, try adding numbers 1 and up to a name formatted as F.Lastname where F is the first letter of firstname.
  7. Last (only performed if the previous combination didn't) add numbers 1 and up to the first part of the email address.
