How do I Control access to password keeper by standard user accounts

I set up standard user accounts for my three Grandchildren. They are not proficient but are capable of using a PC. My concern is that I use Google Chrome & have a password keeper extension that is set to automatically log me into my bank & PayPal accounts as well as Amazon & other such sites. I have always been the sole user on my PC & no one has ever been allowed on it without my supervision. I think I am going to have to change some things but I don't know where to start to do this. The kids are 17, 15, & a pretty savvy 9-year-old.

Many Thanks,

Which password manager are you using ? I use Lastpass which has an add on for Chrome, Firefox and Edge, all of which I use and it works across all 3. For financial sites like bank, paypal or eBay, etc I have those set up to prompt for a master password so guests can't access without it.

Hi Guys,

I have been using True Key but find it very intrusive so I am in the testing stage with Last Pass Free. I have not tested it on their accounts but will do that with both True Key & Last Pass. I will post the results later today.

Many Thanks,

Okay, I tried logging in to their accounts. The good news is, they would need my master passwords to get into my personal sites. The bad news is that when I change settings or disable chrome extensions on their account, I have to re-enable everything when I go back to my account. They also have the option to 'run as administrator'. I am assuming they would need to log out of their account & log into mine to do that. I am not comfortable with having to redo all my settings in chrome & then undo them before I log out.
