How do make username and password access for mu vi

[BFeigum]

If you want to just prevent somebody from accessing your VI, you can set a password by following these directions.

If you are asking how to setup a scheme for your VI where a user can gain certain permissions depending on their user name and password, you will need to setup a manual permissions handler in your VI. For example, you could have a lookup table with a set of known user names which links to a permission level string. Each time you want to run a VI, you can pass in the permission level string and handle it in the VI (e.g. case structure).
