2 of my colleagues lost their personal accounts (which they had linked to the corpo account) when they disabled/deleted the trial corpo account.

They were the only 2 of us who were trialling the linked account approach so I cannot say what the chance of losing your personal account is/was under this scenario.

This was a couple of years ago but understandably prompted a mass migration way from LastPass.

I understand, we've also been talking to LastPass in the past and they offered us something like this (not sure if it's a similar deal). Basically giving employees full access to the paid features personally as well.

But a single login is something I wouldn't even want. If my corporate account got blocked for some reason (e.g. the company folding), would that also lock the personal one? I don't know if we asked them this question as I wasn't directly involved in the discussion. In the end the whole deal was shelved anyway.

For me it's just a matter of account hygiene. And for personal stuff I prefer to host my password manager myself anyway. I was into mixing work/private in the past but with the increasing sophistication of attackers I avoid it now.

I can see the benefit though, promoting the use of a password manager to users who might not have thought of this in their personal life. I know many people who have never even heard of the phenomenon and still use the same password everywhere. I wonder what's in it for LastPass though.
