Would a function actually work when trying to log into node-red admin ui:

```javascript
 adminAuth: {
           type: "credentials",
           users: function() {
             const creds = require("fs").readFileSync('/run/secrets/nodered-credentials', 'utf-8').split('\n')
             console.log(creds)
             let users = []
             creds.forEach(usercreds => {
               users.push(
                 {
                   username: usercreds.toString().slice(0, usercreds.indexOf(':')),
                   password: usercreds.toString().slice(usercreds.indexOf(':') + 1).replace("$2y","$2b"),
                   permissions: "*"
                 }
               )
             })
             return users
           }
        },

```

The value under `/run/secrets/nodered-credentials` is an `htpasswd` something that looks like:

```
admin:$2y$08$x9dYJIaLtdGXFydW2AL9s.YodrBDT3QxYHTcOliBuYSBPAUfHGpjO

```

At the moment in my `settings.js` file I can console log the values but I cannot log myself in

The console log for `users`

```auto
secure_nodered | [
secure_nodered | {
secure_nodered | username: 'admin',
secure_nodered | password: '$2b$08$x9dYJIaLtdGXFydW2AL9s.YodrBDT3QxYHTcOliBuYSBPAUfHGpjO',
secure_nodered | permissions: '*'
secure_nodered | }
secure_nodered | ]

```

Hi!  
Are you aware of [this documentation](https://nodered.org/docs/user-guide/runtime/securing-node-red#user-permissions#custom-user-authentication)?

Yes, it does - when setup accordingly.
