Ask HN: How do you securely enter your LastPass Master Password on Android?

I have installed LastPass on my Windows PC and secured it with a strong, complex password. Now it is time to enter that password on my android phone. How do you get that password securely transferred from the PC to Android? I can, of course, type it in (which you have to do frequently) email it to my self, store it on Dropbox in plain text, etc., but I don't want to do that. It is the master passwords to my other passwords I then have to either share with external cloud service or place in plain text on an Android operating system that hasn't received any updates for years. It surprises me that LastPass has no QR code option or similar allowing me to point my camera towards my pc monitor and securely set up a phone. My current solution is to use an easy-to-enter-password and then only use LastPass for sites I do not care so much about like blogs and similar websites that have no financial or sensitive info on me. Entering a complex password, again and again, is something I don't want to do. Maybe I have overlooked something in settings? What do you do?
