AADSTS50012: Authentication failed.

Question

AADSTS50012: Authentication failed.

Ishwar Pawar 1

Hello! I am having the sae problem. I recently created a new user for a new memeber of my organization. I gave her the credentials and when she does the first log in, it requires the username to set up a password (as the password provided by microsoft is temporary) once she sets up the new password, this error happens. So she isn´t able to log in.
I tried doing it myself and effectively it is not possible to log in.

I'm also running into this issue over the last few days. I've attempted to log in to the account on my end within a private window and also get the same error.

Sorry, but we’re having trouble signing you in.

The password she is setting will not be complex enough - it might contain a phrase etc. I have just had the same issue and it only worked when I used a completely random/complex password.

Hi,
We are facing this similar issue from last couple of days.

We tried following some of the suggested solutions of setting easy and complex password but no luck
Also created a new user by selecting create/enter a password manually.
But in every case it prompts us to enter the temporary password and then create a new one, which eventually gives this "AADSTS50012: Authentication failed." error.

Any luck on this?

Hi Naina,

Can you please provide the sign in and audit logs for this users, please download and zip it to the onedrive and share it. If everyone on this page can provide me signin logs and audit logs will be great to investigate this issue.

Thanks all.

Hi All!

Same problem here. Simple and Complex passwords give the same authentication error when the user is forced to change it due the expiration.
Please let us know if you find any solutions on this issue.

Thank you.

I had to manually set a password and set it to not force the user to update. I then had the user manually update the password. This is the only way I could get this to work today.

I found a workaround!

Go to change their password in the Admin panel, but uncheck the box that makes them reset their password after logging in with the temporary password. Once they log in with the password you've assigned, they can gain access to their account and then manually change their password in the settings.

@Jami Moore This more or less was what worked for us as well. We're sync'd from on-premise AD and removed the 'change password at next login' flag for new users and they were then able to login to do their first time MFA setup. After that they're able to go through any which password reset option.

Answer 3

Hello everybody and thanks a lot for reaching out. My understanding is that you're encountering the AADSTS50012: Authentication failed error whenever A. A new user tries to set a new password and/or B. A new user tries to set a new password once the initial one has expired. For the latter case and as a possible work around create the user using AzureAD PowerShell o Microsoft Graph PowerShell (Or API) setting the passwordProfile as "DisablePasswordExpiration". Eg.

AzureAD

   Connect-AzureAD  
   $PasswordProfile=[Microsoft.Open.AzureAD.Model.PasswordProfile]::new("string", $true, $false)  
   New-AzureADUser -DisplayName "string" -PasswordProfile $PasswordProfile -UserPrincipalName "string" -AccountEnabled $true -MailNickName "string" -PasswordPolicies "DisablePasswordExpiration"

Microsoft Graph PowerShell

   Connect-MgGraph -Scopes "User.ReadWrite" # Or -AccessToken "string" where "string" is an access token with User.ReadWrite or superior scopes  
   $PasswordProfile = @{ ForceChangePasswordNextSignIn = $true  
   Password = "1234" }  
   New-MgUser -DisplayName "string" -PasswordProfile $PasswordProfile -UserPrincipalName "string" -AccountEnabled -MailNickName "string" -PasswordPolicies "DisablePasswordExpiration"

In any case, if the issue persists, please post debuggin information: correlation-id and timestamp so we can better analyze it.

I will be waiting for your comments.

Answer 4

Hi,

The error code points to one of this :

AADSTS50012 AuthenticationFailed - Authentication failed for one of the following reasons:

The subject name of the signing certificate isn't authorized
A matching trusted authority policy was not found for the authorized subject name
The certificate chain isn't valid
The signing certificate isn't valid
Policy isn't configured on the tenant
Thumbprint of the signing certificate isn't authorized
Client assertion contains an invalid signature

Check if user is having any conflicts from Onpremise? Also check like Device is having any user certificates that require renewal? Try the process from another PC or incognito browser.

Hope this helps.
