### 26.4. Change user

At startup, we login automatically as the `root` user.

If you want to switch to another user to test some permissions, we have already created an `user0` user through the user_table file, and you can just login as that user with:

    login user0

and password:

    a

Then test that the user changed with:

    id

which gives:

    uid=1000(user0) gid=1000(user0) groups=1000(user0)

- Login as a non-root user without password
