Not clear yet what exactly OP is asking for. On the one hand, they seem to want to disable (or eliminate) the master password, but on the other hand, they wish to introduce back doors for account recovery (something that Bitwarden has deliberately avoided for security reasons). @W01V3N, is this an accurate summary of your proposal?
Personally, I think that introducing back doors for account recovery (e.g., recovery codes or password reset emails) would be much less secure than simply keeping the master password as a fallback option if/when passwordless login fails. If someone can get your master password, why wouldn’t the same attacker also be able to get your recovery code or email password?
This part of your post was also confusing. Why are you changing your master password “often”? That is definitely not recommended.
