[Feature Request] "Soft" password & PIN code

[eucalypto]

I think there is already a thread and vote for this:

Unlock vault with PIN

Add the ability to “lock” a vault with a PIN code, similar to the mobile apps. NOTE: Since the browser has no method of securely persisting the encryption key, a user would still be required to enter their master password upon browser restart.

I do agree with your proposed details. I would really like to see this feature.
