is there a way to add a biometric, preferably a fingerpint, lock to you Electrum wallet?
I would like it on top of my normal password, just in case.

I prefer the simplicity over normal 2FA, which can easily be lost.

no there isn't.

you're 2fa wallet can be restored from seed. the seed is only displayed at the time of wallet creation so if you haven't written it down create a new wallet and move your funds there. otherwise if you ever lose your phone you won't be able to recover your 2fa wallet and will lose money.

You can do this with most iOS or Android online wallets like Copay or Blockchain. However no cold storage option that way.

I am thinking deeply how they can scan your finger print the touch screen it can only receive touch but it can't scan any fingerprints almost all fingerprint apps in playstore are actually all are fake no good fingerprint app that actually it can scan your fingerprints.
Well backuping seeds for is still be good i still never had any problem to my electrum wallet and local bitcoin wallet which is coins.ph.. with google authenticator..  its much safier i can't even login even i recovering it in gmail.

You could possibly rig up this to a raspberry Pi and code something that could do the job for you?

Not a expert in this field but a quick github search found this.. for Arduino

I use it already for my mobile blockchain wallet, that is why I thought about it for Electrum!
It certainly makes it easy, and for my mobile wallet it is much safer than a 4 digit code!  I only keep a small fraction of a bitcoin on my phone, but that is still a fair chunk of change nowadays!

For Electrum I would like it as a 2FA. I use 2FA already, but if I lose my phone, or I don't have it with me, it means I have to restore my wallet from seed, which isn't ideal. 
I would like to type in my seed as infrequently as is possible, in case of keyloggers or alike.
