ohhh maybe a way to password protect when you start ttth seens your logged in to all your services

it could be helpful - most likely for those using the autostart.

Question is:

• should the user be able to lock the running session at any time? YES
• How to define and store the password? OPEN

Problem:

• need to store a password or its hash somewhere on the computer.
• need to store the lock-state somewhere on the computer
• If someone has access to the computer, the fs and the DevTools its easy to bypass this locking-feature.

Quote from riot chat

why lock functionality is needed?
you have operating system screenlock for that
on windows, mac and linux (depending what window manager you are using, ymmv)
you guys always lock your computers when you go for coffee, right?
imho that lock feature is bit overengineering and unneccesary feature which adds to bloat
....
if you have control over machine
you can do whatever you want
so this "protection" is snakeoil

... well - its true ;)
