dose not log out when i close teamviewer on android.

Hello,

i have download teamviewer on my phone and i got it double verification. the problem is when i close the app and press to enter again its automatically logs in with my account. what im looking for is that i want to write again my password every time when i enter the app.

on iphone you can change it on the settings but on android u cannot do it. 

please if you have a soultion let me know 

Regards,
