Windows 10: At&t wanting to install certificate?

This is the first time I am seeing this and have had this service for a month and never received this message so I'm not sure if it is valid or not. I tried going to my account on AT&T and a request popped up asking me to authenticate myself with a certificate wanting me to download. I don't know if I should or not. I'm unable to get in touch with AT&T tech to ask and am unsure if I am even chatting with AT&T now that this has happened as I have been dealing with spoofing and hacking for years. I was looking info certificates prior because of security issues and trying to mange m

Install of SDK Certificates on ATT Tilt Blocked

I couldn't find the script i had created but if you have a registry editor for the tilt you can follow the following steps if not the I suggest resco registry editor which can be found at handango.com. Its not a free program but you can download the 30-day
trial and since all you need to do is modify a registry entry and unless you do a hard reset you won't have to do it again.

• 
  find HKLM\Security\Policies\Policies.
  

[*]

• Change the following registry items:

• 
  00001001 overwrite the 2 with 1
  

• 
  00001005 overwrite the 16 with 40
  
• 
  00001017 overwrite the 128 with 144
  

• 
  Now, it is possible to download the certificate from the server and install
  

 

N8 certificates not trusted/don't match the name

Well I worked out for myself how to verify the certificates are genuine:

• Using a desktop computer
• Go to the page with the certificates
• Select a certificate
• It will say either:
  • Certificate already exists - this confirms that the certificate on the website matches one already in your browser, which we already trust, therefore the certificate on the website is trustworthy
  • Asks if you want to install the certificate, DON'T.
    • First view the certificate details.
    • Copy the certificate serial number or SHA1/SHA256/MD5/etc hash
    • Paste this into a search engine
    • If another website that you trust lists the certificate, e.g. your phone manufacturer or another trusted website (preferably a secure website, therefore you have confidence the website is genuine), then you can trust the certificate
    • If no trustworthy sites are returned in the search then try another hash or serial number
    • If you can't find any trustworthy sites listing the certificate then I suggest you don't trust it.
• Finally, if you decide you trust a certificate then you can download and install on your phone.

 

Unable to install Trusted Certificate for WORD

Hello! Bryan Koyano

Thank you for posting in Microsoft Community

The error message you’re encountering while trying to install a trusted certificate for Microsoft Word indicates that the certificate used to sign the deployment manifest for the add-in is not trusted. Allow me to ask:

• Is this happening to other Office programs?
  
• What version and edition of Office do you have installed in your device? Example: Personal/Family/Enterprise?
  
  • You can open any Office apps
    
  • Go to File > Accounts - on the right side you can see Product Information
    
• Is this happening to other devices? or just this device?
  
• Have you tried uninstalling/reinstalling the Office on your device?
  

Here are some steps you can take to troubleshoot and resolve this issue:

1. Check Certificate Trust:
   
   • Ensure that the certificate you’re using is valid and trusted. If it’s self-signed, make sure it’s added to the trusted root certificate authorities on your system.
     
   • Verify that the certificate’s location (file path) is accessible and not blocked by any security policies.
     
2. Office Add-In Trust Settings:
   
   • Open Word and go to File > Options.
     
   • Select the Trust Center tab.
     
   • Click on Trust Center Settings.
     
   • Navigate to the Trusted Locations tab.
     
   • Add the folder containing your add-in files (including the certificate) as a trusted location.
     
3. Uninstall/Reinstall office.
   
   • Go to Start menu > Settings > Apps > Installed Apps.
     
   • Locate your Microsoft Office and click Modify
     
   • Click Uninstall and follow the instructions for uninstalling Office.
     
   • Restart your device.
     
4. To reinstall Office in your device:
   
   1. Go to https://account.microsoft.com/services/ sign in with your account.
      
   2. Click the Install button - this should download your Officesetup.exe to your device.
      
   3. Run the Officesetup.exe
      
   4. Follow the steps for installing Office in your device.
      

Remember to consult your system administrator if you need further assistance. Hopefully, these steps will help you resolve the certificate trust issue and successfully install your Word add-in!

I hope this helps!

Thank you,

Vince
