BlockFi mobile app is insecure!

Suggestion

I opened up the app after days of not using it and it let me in without any authentication. I could see my portfolio and was able to initiate trades, no problem!

All finance apps implement at least a device PIN, that is asked from the user after the app goes inactive. That is a bare minimum security measure!

Until this is implemented, i advise everyone to not use the mobile app!

Few weeks ago I logged into my account to look, then I explicitly logged out and my girlfriend went to log into her account right after on the same computer - she went to the home page, then clicked the login button, put in her email and password and then was logged into my account.

Tried to recreate it but couldn't.

You can turn on biometric security

Fingerprint not pin. Please not a pin.

Pin for peasants like me who have a phone that does not support it. But yeah, having both options would be great.

Can not reproduce that. if i log out i get asked for mail an passwort + the Auth token

If i close the app my fingerprint is required and after a certain ammount of time i need to log in via pw an auth again

Android or iOS?

I am on Android and I was able to just open the app. Which is what you are seeing. This is not going to stop me from using the app though as you need a pin or face to unlock my phone.

I would like to say that I also just opened the app after not using for days and it just opened and I was able to trade withdraw etc I find this super sketch

Yeah, but instead of pressuring BlockFi to fix their shit, people prefer to downvote any critical thread.

What a nice community.
