I would prefer if they would ease the creation of temporary Mails instead of hiding it in the settings. Yeah me too. I wish they’d integrate with Bitwarden’s e-mail address generator. If you e.g. use anonaddy you just paste a anonaddy apikey into Bitwarden and it creates e-mail aliases in anonaddy for you.

Though it would be nice to just use the e-mail alias service from your existing e-mail provider (as you describe with mailbox) rather than buying another 3rd party service.
