User story : Apple’s Hide My Email works to generate email addresses that forward to a primary source address. This provides security and organization for generating accounts behind a layer of obfuscation. What is Hide My Email? - Apple Support
Bitwarden already offers integration into a number of services that provide this same functionality referenced at your help page : Add Privacy and Security Using Email Aliases With Bitwarden | Bitwarden Blog
Ask: Bitwarden integrate into this Apple offering so that email addresses can be created in browser/vault, saved to the Bitwarden locker as a login medium and forwarded to source address.
As of right now, this is a two step process in using both services. A user has to navigate to the Apple ‘Hide My Email’ feature, create an email alias, save that email alias, open Bitwarden, create a new object, paste newly created apple email alias in and save settings.
