IPad how to delete old user

What you should do is totally erase the device if the iPad is now yours and no longer belongs to the company. You will not be able to use any purchased content that they supplied on the device unless you use their Apple ID and password - if that is how the process worked in the company.

Anyway you can go to Settings>Store> and sign out of whatever account the iPad is signed into and then sign into your own account.

To erase the devie completely and truly make it your own go to Settings>General>Reset>Erase all content and settings.

Would this erase everything from my iPad including all apps and games ? Also would I be able to use the old accounts ??

You are most welcome 🙂

Setup as new

Settings>General>Reset>Erase all content and settings
