think about a standardized property for different auth mechanisms in user objects

[foxriver76]

• like LDAP #1142
• or https://github.com/Vertumnus/ioBroker.googleauth
• I could think of common.authentication which is an object, containing a name/id of the service/type + additional auth type specific information

[Apollon77]

I would propose more a common.externalAuthentication as name for the field to show that it is about "non iobroker" authentication mechanisms.

externalAuthentication: {
    "google": {
        "id": "...",
        "...": "..."
    },
    "ldap": {
        ...
    "
}

with id being always there and other keys could contain access/refresh tokens or whatever
