Security problem

[rpshi]

I set up password using tools -> security -> user and group accounts.
After that, I cannot logon again. And I'm sure I have the correct password.
Is there any way to find the logon information or to reset password?
Thanks.

Have you tried signing in as Admin and use a blank password?

The problem is how to sign in as an admin.

Unless you revoked the default user 'admin' rights, you should still be able to sign in as 'admin'.

you mean using the logon name "admin"?
I tried but failed.
