The importance of passwords are different. Some passwords are so important, some passwords are not so important.
- Examples of important passwords: bank, trading, credit card, PayPal, sns, email accounts, etc.
- Examples of non important passwords: entertainment, shopping, point card, forum accounts, etc.
Important passwords should be treated more carefully than non important ones.
I think it's better to introduce multi level protection to keep them more secure and require additional factor authentication for important passwords and secure notes.
Most of important passwords are used less frequently than non important ones, it may not be so burdensome.
a. non important level session: only non important passwords and secure notes are allowed to access
b. important level session: all passwords and secure notes are allowed to access
You enter a. after you login to LastPass.
You move to b. after you succeed in the additional factor authentication and move to a. after some time passes.
Non important passwords should be enabled when you first login to LastPass and important ones are disabled at that time.
With additional factor authentication, you can access to important passwords for some time and log off from the session automatically.
You can access non important passwords even after logging off from the important level session.
