Why can't l set lockscreen password

[Android Central Question]

Everytime l set the 6digit password it never locks rather takes me back to the starting page with options for setting password and l always swipe to unlock phone

Is it a bad phone, perhaps? https://forums.androidcentral.com/ask-question/1025678-asking-your-question.html

Welcome to Android Central! Which phone? Has this always been your phone?

When you put the 6 digit password and ask you to re-enter it again you put the same one ?
