Using 1password on work or other someone else’s computer. How do you?

Hi @jb60202!

If you have a 1Password Membership, you can login to a different computer directly on the 1Password.com website, using the information in your Emergency Kit ;)

how 'safe' is this ? in regards to, once your gone what traces are left (if it was a one time login thing)
and how would a (unkown) keyloggers break this ? and would the 2FA make this ALOT better, or not so much ?

@gadget78:

how 'safe' is this ?

It's as safe as the computer you are using. If you don't trust the computer, you should not perform any sort of sensitive operation on it.

in regards to, once your gone what traces are left (if it was a one time login thing)

If you tick the This is a public or shared computer checkbox on the 1Password.com login page, your credentials will not be remembered on that machine.

and how would a (unkown) keyloggers break this ?

If you are using a machine with a keylogger installed, everything you type on that machine can be recorded. There is not much an app can do to protect you on an already compromised machine: if you suspect that a computer might be infected with a keylogger, you should avoid using that machine to login to your 1Password account there.

and would the 2FA make this ALOT better, or not so much ?

Not so much: your data is still encrypted by your Master Password and Secret Key, not by your 2FA codes. So if those are exposed because they were caught by a keylogger, you should still change your Master Password and your Secret Key for good measure. The effort might not be worth it if you could simply avoid using an untrusted computer in the first place.

Also note that, in this case, "untrusted" does not mean that you are absolutely sure that the computer is infected; it simply means that you don't know whether it is safe or not. So it is a safe assumption to consider it not safe.
