Phone is unlocking without asking for passcode. How do I change this? (Nexus 6)

[lifesucks2020]

So earlier today I got a google play services permission asking me if I want to keep my phone unlocked in places such as home, and I accidentally said yes to it. Now my phone just unlocks without even asking for the passcode. I want to change this, I want it to ask me my passcode. How do I change this? I don't want anyone else going through my phone. Please help!
