Absolutely, only thing not allowing me to migrate to Proton from Bitwarden. And it shouldn't be just master password, you should be able to add your own password to specific entries if you wish.

We all have many secrets. Some secrets are just passwords for not very important services like Reddit, etc. But we also have some very important secrets that we want to protect with the best security. Bitwarden, my current password manager, has a "Password Required" feature that requires me to re-enter the password to view some secrets even when my vault is unlocked.

Proton Pass already has an Extra Pass feature, but this password is enabled at the vault level. Users will not need to enter the password when a vault is unlocked.

Imagine that the user wants to log in to some website like Reddit. It may cause a very bad experience if the user needs to enter the password every time. But for something very important, like a credit card number, the user may not want to access the information as easily as a Reddit password. An additional step (re-entering the password) is acceptable here.

I also suggest that the Extra Password feature can be enabled for selected items only. That will allow the user to set a value that is simpler than the main password. Requiring the main password is very hard for me because my main password is very long and complex (considering it protects my email, files, and crypto, this is fair).

I use this feature in dashlane with secure notes to store my 2fa recovery codes. Fantastic feature, would like to see in proton pass

Much needed option as I would like to separate the accounts I use to purchase coffee from my retirement accounts.
Best Use Case would be minimal friction access into ProtonPass on mobile and desktop; such as a pin. I would avoid bio authentication due to risks of using immutable tags to build a dossier of the individual.
Within ProtonPass low value logins are in unlocked vaults, such as coffee shops or the trampoline park you visit once a year.
High value logins could be locked in password and 2FA protected vaults, such bank logins, retirement accounts and, medical databases.
The user could create multiple vaults with security levels based upon content, maybe the power company and water bill shouldn't be stored with coffee shop logins but storing with retirement accounts is overkill.
Crossing my fingers this gets traction so I can combine the completely separate password manager accounts I currently use for this purpose.

I need a vault to store credentials I don't want to be suggested anymore, but still want to keep.

YES PLEASE!

Both Bitwarden and Norton allow users to set a requirement to re-enter the 'master password' in order to view any particular entry in the vault.

Ideally, this would be a configurable option so that one could set it as:
1. Master Password required for Auto-fill to work AND to View or Edit the Login details in Pass. or,
2. Auto-fill does NOT require Master Password to work, but Master Password IS required to View or Edit the Login in Pass.
3. OFF

I am yet to find a single Password Manager, whether in a free or paid tier, that has ALL the features it should have.

This is a very helpful feature i feel

Possibility to add secutity on one vault at least is very important.

I also miss this functionality from lastpass.

E.g:
For wallet 1 fingerprint will unlock.
For wallet 2 you will need fingerprint and additionally Yubikey/Authentikator to unlock.

Enhanced Security:
Empower users with the ability to lock individual vaults for example Personal and Work Vault.

Tailored Privacy:
Customize security measures for your most sensitive data.

I recommend introducing a new feature that allows users to lock individual vaults within the app. This feature would significantly enhance security and privacy, offering users a tailored and customizable way to safeguard their most sensitive data of their Personal or Work Vaults. For instance, consider being able to share your WorkVault password with a colleague to grant them access to specific information without compromising the privacy of your Personal Vault. It's a valuable addition that can set your app apart in terms of data protection and user satisfaction.
