AC Question

Phone model: Asus zenfone go 5.5

I was exploring Android Device Manager with my new phone, and I clicked the Lock feature and it locked my phone. My phone's not lost. It's with me, but I can't unlock it. I already unlocked the password that ADM was asking, I also called the number I set to call in case it was lost, but after that, it's still asking for another password. All the passwords that I know, or previously set in the said phone is not working. I don't know what kind of password it's looking for.

I hope you could help me.

Thank you!
