Yes, I use a high entropy passphrase. 256 bits or better. An easy secure way to create a high entropy passphrase\password is with one of the keepass clients.

I like keepass2android for Android. Mine is optimized and hardened. Also as you know. Don't store your seed and passphrase together. If you lose either one though, you're screwed. And don't store your seed words online etc..👍🧡😊
