#Site Certificate
$cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2(“C:\yourpath\Authcertificate.cer”)
new-SPTrustedRootAuthority -Name “ADFS4.0Auth” -Certificate $cert

clear
# ADFS Certificate
$cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2(“C:\your token provider certificate path”)
New-SPTrustedRootAuthority -Name “ADFS4” -Certificate $cert
$ti = Get-SPTrustedIdentityTokenIssuer
$ti.ProviderUri = ‘https://yourADFS domain/ADFS/ls/‘
$ti.SigningCertificate = $cert
$ti.update()
