Are your passwords similar in the first few chars? ex:

thisismypassword12345 thisismypassword54321

I've heard of password hash issues (amazon had this problem) where they only used the first 8 chars of a password when generating the hash that they stored.

Afraid not. My passwords are ones that I made up and just kind of got used to typing, without giving too much away as to what they are...they're completely different and just words/numbers that have no meaning really.

That is strange. You should report it to google's bug bounty program so that they can triage it or get it to a group that can fix it. (I'm not sure of another avenue to get through to a person there.)

Indeed it is. I'm afraid Google only have their own bug bounty program and I think PayPal no longer have one.

In terms of where to go from here I've no idea.

If you asked the google bug bounty program about it, I'm sure they'd either answer for youtube, or send you in the right direction. While unlikely, I wonder if it was some kind of hash table collision. If you change your password again that might solve the issue if that was the root cause (a guess).
