Possible reasons:

1. An invalid password or customer ID has been entered

• E.g. by inserting the password via copy & paste

  (Special characters can possibly get copied with the password)

2. Too many failed login attempts

• Wait for the end of the displayed lock period and try again

• Use the „Lost password?“ function to have a new password created after the lock period has been suspended

3. Your account is deactivated (locked)
