How to open app using Google Assistant when phone is locked?

[Sammuel1973]

It was working perfectly until today. Now, I have to unlock my phone via pattern or fingerprint. Before when I say, "OK Google, open YouTube.", it opens the app immediately without needing to unlock via pattern. Thanks for any help.

Yeah that's a security feature , you have very minimum use of Google assistant on lock screen
