It is legal for a coworker to ask for you password. You are not required to oblige that request. Also, it might be against company policy for you to oblige that request.
If she is married, you are screwed. If not, then it is legal to ask her out on a date. Of course one should not get too obtrusive.
If you want to ask out your mom's coworker, you are just sick
If you ask them to use it and they say yes and give you the password, then yes it is legal. If you use it with out asking and hack their system, then no it is not legal.
if it is a female coworker than yes but if male no
If the request is reasonable, and doesn't interfere with your tasks and responsibilities, help the coworker. If it does interfere with your tasks, ask a supervisor what to do.
format it or ask for password.
it wouldn't be rude to ask them what their family does if you know this said coworker well. you may want to ask them over dinner of a coffee. i wouldn't just jump right in and ask them at the interview. they may think that you are to nosey and you might not get the job. so just play it by ear and see where the coworker relationship goes. hope that i helped you. you can reach me at my e-mail anytime.
You must have the password, there's no legal way around it.
Ask nicely why she did it. (or find out the password.)
When logging in, you must log in with a password and username. When contacting them about issues or questions, they may ask for the account id and password.
Hiring that coworker
It has been set up to ask for a password or is performing a task that requires a human to authorize.
