I will try and explain as much as I can.

The MemberModelBuilderFactory initialises the model, example below

// Build a registration model with parameters
var registerModel = memberModelBuilderFactory
    .CreateRegisterModel()
    .WithMemberTypeAlias("forumMember") //If you have a custom member type you can set it here
    .WithRedirectUrl(null) //you can set a url to redirect to after registering
    .WithCustomProperties(true) //this will allow you to get values for any custom properties you may have defined
    .UsernameIsEmail(false) //default is true
    .Build();

If UsernameIsEmail is set to false then you must provide the username in your form, other wise it defaults to the email address.

Now in your registration form you can ask for these fields from the model declared above

1. Name //this is the Name, if not set it will also default to the email i think
2. Username // if you have not set UsernameIsEmail to false this will automatically be set to email
3. Email
4. Password
5. ConfirmPassword

If you have any custom properties then you can display those using

@if (registerModel.MemberProperties != null)
{
    for (var i = 0; i < registerModel.MemberProperties.Count; i++)
    {
            <div class="mb-3">
                <label asp-for="@registerModel.MemberProperties[i].Name" class="form-label"></label>
                <input asp-for="@registerModel.MemberProperties[i].Value" class="form-control"/>
                <input asp-for="@registerModel.MemberProperties[i].Alias" type="hidden"/>
                <span asp-validation-for="@registerModel.MemberProperties[i].Value" class="form-text text-danger"></span>
            </div>
    }
}

You don't need the MemberModelBuilder for login, just the LoginModel

@using Umbraco.Cms.Web.Common.Models
@using Umbraco.Extensions
@{
        var model = new LoginModel();
}
<div class="login-form">

    @using (Html.BeginUmbracoForm<YOURMemberController>(
    "HandleLogin", new { RedirectUrl = Model.RedirectUrl }))
    {
            <hr />
            <div asp-validation-summary="All" class="text-danger"></div>
        <div class="mb-3">
            <label asp-for="@model.Username" class="form-label"></label>
            <input asp-for="@model.Username" class="form-control" autocomplete="new-password" aria_required="true" />
            <span asp-validation-for="@model.Username" class="form-text text-danger"></span>
        </div>
        <div class="mb-3">
            <label asp-for="@model.Password" class="form-label"></label>
            <input asp-for="@model.Password" class="form-control" autocomplete="new-password" aria_required="true" type="password" />
            <span asp-validation-for="@model.Password" class="form-text text-danger"></span>
        </div>
        <div class="mb-3 form-check">
            <input asp-for="@model.RememberMe" class="form-check-input" aria_required="true" type="checkbox" />
            <label asp-for="@model.RememberMe" class="form-check-label">
                @Html.DisplayNameFor(m => model.RememberMe)
            </label>
        </div>   
        <button type="submit" class="btn btn-dark">Log in</button>

        }

</div>

Context.User?.Identity(?).Name retrieves the LoginName

Ii is from the .net authentication cookie, it is using standard microft identities https://learn.microsoft.com/en-us/aspnet/core/security/authentication/identity?view=aspnetcore-6.0&tabs=visual-studio

MaxFailedAccessAttemptsBeforeLockout

I have not tested, but it should still work in dev the same

Thanks for the reply! Much appreciated!!

to be more clear, there are 4 forms: registration, edit, login and the login status.

In registration Model.Name Model.Email are declared.

<td><input asp-for="@registerModel.Name" class="form-control" aria-required="true" /></td>        
<td><input asp-for="@registerModel.Email" class="form-control" autocomplete="username" aria-required="true" type="email" /></td>

In edit, Model.Name Model.Email and Model.UserName are available. (I wish password was there by Umbraco default). Notice UserName is new. UserName is the first value required to login (besides password).

    <td><input asp-for="@profileModel.Name" class="form-control" aria-required="true" /></td>
    <td><input asp-for="@profileModel.Email" class="form-control" autocomplete="username" aria-required="true" /></td>
@if (!string.IsNullOrWhiteSpace(profileModel.UserName))
        {            
            <td><label asp-for="@profileModel.UserName" class="form-label"></label>Login</td>
            <td><input asp-for="@profileModel.UserName" class="form-control" autocomplete="username" aria-required="true" /></td>
            <td><span asp-validation-for="@profileModel.UserName" class="form-text text-danger"></span></td>           
        }

In the login form you need to provide Model.Username and Model.Password.

<td><input asp-for="@loginModel.Username" class="form-control"/></td>

Now where did Model.Name go? In the login status I can retrieve the UserName and authentication status:

   <a href="/edit-login/"><strong style="margin: 1px 10px">@Context?.User?.Identity?.Name</strong>
        <a href="/edit-login/"><strong style="margin: 1px 10px">@Context?.User?.Identity?.IsAuthenticated</strong>

        @using (Html.BeginUmbracoForm<UmbLoginStatusController>("HandleLogout", new { RedirectUrl = logoutModel.RedirectUrl }))
        {
            <button type="submit" class="btn btn-primary">Log out!!</button>
        }
        </a>

I find this confusing, because .Name displays the UserName which we declared in the registration model as Model.Email and not Name. Also, what other information is in such a cookie? Not email address or custom properties is presume.

In SQL i cannot find the original value for Model.Name. I think I've checked all collumns from tables :-) The link you gave me says the information should be in dbo.AspNetUsers but that's not the case in our case. It should be easy to find in SQL right? Or is this a false assumption. In SQL I find LoginName and Email. Login Name corresponds to UserName (which we declared as email and is displayed in status as Name from the cookie) and Email to Email.

I understand the UserName (or LoginName?) is retrieved from a cookie when logged in. Does it make sense to retrieve something like the original value of Model.Name and show that (how?) or would you not advise this.

about registration: when i set .UsernameIsEmail(true) in the registration form as parameter for the memberModelBuilderFactory when I build the registerModel and set the value in appsettings.json

 "Umbraco": {
    "CMS": {
      "Runtime": {  
  "MaxQueryStringLength": 90,
  "MaxRequestLength": 2048
      },
      "Security": {
        "KeepUserLoggedIn": false,
        "HideDisabledUsersInBackOffice": false,
        "AllowPasswordReset": true,
        "AuthCookieName": "UMB_UCONTEXT",
        "AuthCookieDomain": "",
        "UsernameIsEmail": true,

It does not seem to change much. Perhaps because the collumn in the table in sql is already there... i can still change both seperatly, they are not linked, So confusing!! Hope I can add some comments to the project some day to make this more clear! Tnx in advance

I might have some of my terminology or facts wrong here, and im still on V10 but my two cents below are based on what I have found:

Umbraco uses .net core identity under the hood. It uses a custom implementation of the stores though, so you wont find a "dbo.AspNetUsers" table like a vanilla implementation of identity. For members, youll find "cmsMember" and for users, youll find "umbracoUser". These tables, as you have seen, store the basic values used by .net core identity.

However, apart from the basic values used for authentication, the members are stored as nodes, in a similar but slightly different way to all other content.

If you go into Settings > Member Types > you will see the different member types. When you create an instance of one of these, you are creating a content node to store the data, just like a page in the CMS.

If you want to find where the member name is in the database, you need to find the node in the [umbracoNode] table.

SELECT * FROM [dbo].[umbracoNode] where text = 'Name of User'

If you need to find the values of custom properties of a member in the database, you need to look at the [umbracoPropertyData] table.

Its probably best not to try to decypher the database though. I think all you need to use in any custom code is IMemberService for updating the member data and MemberManager for updating usernames, passwords etc...

Its not an ideal implementation IMO. The more members you have, the larger the content node and property tables get, the slower the queries become etc.

Updating member properties actually lock the content tables entirely too. I learned this the hard way trying to import members in parallel a rake load of them failed. Essentially, because of the locking, you can only create/update/delete one member at a time, in the same way as a piece of content in the content tree.

I have 400,000 member records and have found the above issues too much of an issue for us, so we are moving away to a custom .net core identity implementation + identity server. But if you are expecting 100s or 1000s of members, it should be no problem at all.
