What does the "Set Master Password" function in Winbox do?

I was unable to find any reference to its' function searching the forum, and the documentation for Winbox does not contain any information (http://wiki.mikrotik.com/wiki/Manual:Winbox), nor does the changelog (http://wiki.mikrotik.com/wiki/Winbox_changelog) contain any references.

c'mon Mikrotik. Document your stuff!

It encrypts the winbox config file, so all your saved passwords aren't in plain text.

Thanks, though that's a fairly incomplete description.

What is the behavior after encrypting? Does it have to be entered every time winbox is opened?

Yes, that's the idea behind master password - no password, no access to data. Which is great when attacker does not know it, but not so great when you need to type it over and over.

How can I find my master account for the Vienna Box password? I changed the password for Master, and now I do not remember how to get back

You can't. That is the whole point of the password

Hi!
Man who set all details don`t remember the admin password. (or he don`t want to give)
I can enter because of "keep password" click. (I can connect as admin... but don`t know the password)
admin and password has been saved before. I am worrying every time when I enter to that place
For any-cake I made a super-password .
I did backup
I create another "admin user"
For reference attached what I see in winbox, before connecting

I want to get / or change admin password (In the future - don`t want to loose everything )

What are the procedures in my-case. I am a new user and I want to learn step by step how to get my admin password without loosing my datas.
Sorry for my bad-english explaining
Thanks in advance
