Raspberry OS

I am must be a complete noob, I thought I have some technical skills but it appears not. I am trying to connect to my raspberry pi which came with the bootable sd,I have added keyboard and mouse and plugged in to tv, but when it boys it asks for login. not the “pi” and raspberry login. i can not get it to boot into the OS. Can anyone help. I am setting this up for my daughter so she can use scratch in a different way, so benign able to boot into scratch is important.

Can anyone help??

Can you give some more details on how you are connecting to the Raspberry Pi and where you are entering the username and password. The default username is “pi” and the password is “raspberry”. If this does not help, can you attach a screenshot of what you see on the screen.
