Security of Pin unlock with the browser add-on


I would like to know how safe it is to log in to your account with the browser plug-in via a pin instead of the master password. How do you identify the browser/ hardware and how do you ensure that hackers can’t forge it? In any case, what length should the pin at least have?
Additionally, is the same method applied for remembering a device with respect to 2FA?

Thank you for your help!



PIN is not as secure as long and secure master password.
However, PIN can be useful in case you are highly sure that:
a) Computer is not infected and will not be infected;
b) No one from your co-workers/friends knows that PIN.

Overall the PIN is sufficient enough. To steal your vault’s content via malware must be specific targeted attack. I personally haven’t heard any info-stealing trojans that target password manager’s files (to steal their content).
However, this does not mean that they do not exist.

Overall it comes down to your personal preference - do you want to have more security or ease of use.

2FA is another story and I’m afraid I can not comment on that.
