Help please!

I am not very lterate when it comes to routers so would appreciate help. I have Dratek Vigor 2600plus and cannot find a logout button! I have logged in via password and now when I access router it goes straight into admin page without asking for password. I have tried switching router off and on again but still appeared to be logged in. Also just tried closing window and then gone back and still allows access without password.

Thanks in advance

If i remember there is not logout button at the 2600
