What safety measures would you recommend to a novice?

I am a new Binance user, I've already made my first trades, and I'm currently interested in strengthening the security of my account, so I was looking for advice on the subject.

Obviously, my password is super long and consists of random characters and I only trade with verified users with very good ratings, but I have some doubts about the subject:

• Is the Android App secure?
• Saving my password in my browser seems like a bad idea, but do you think I should install a new internet browser just to use Binance? And if that were the case, which internet browser do you recommend?
• What other security measures do you recommend to protect my account?

Thank you in advance for your response.
