Login with Apple ID does not work if it is secured with a Security key as the browser in parallels login tool is to old / unsecure. As it just became normal that logins are not saved anymore and every few days you have to login again to Parallels this is quite anoying, please fix it. Or even better fix it so that you only have to enter your license one and then it is saved.
I have declined to renew due to this issue and converting my account to a "normal" one is not an option. Please fix your authentication system.
