Popular password resets:

password passme abcdefg pass1234 reset changeme late4work

I am sure there are others, once the password is changed to one of these easy passwords, someone who owns the account is support to change it to a harder password.

I used to work as a federal contractor and in IT departments and handled password resets.

One time as a federal contractor someone phoned in from Florida to pretend to be me or someone in my group to get our account password changed to one of the above. They used social engineering and might have been someone who worked there but retired.

When you have a weak password, people can easily break in.
