Upgrades are needed for 4.5.1 and Google Page Insites Hash Algorithm's from SHA 1 to SHA2-128 bit or to 512 bit HMACSHA512.

I tried to use it with autogenerate as below at:, but my shared server did not like it.

  validationKey="AutoGenerate,IsolateApps" [String]
  decryptionKey="AutoGenerate,IsolateApps" [String]
  validation="HMACSHA256" [SHA1 | MD5 | 3DES | AES | HMACSHA256 | 
    HMACSHA384 | HMACSHA512 | alg:algorithm_name]
  decryption="Auto" [Auto | DES | 3DES | AES | alg:algorithm_name]

So I found at: capable of 512 bit HMACSHA512.

Online Machine Key Generator

Description: This tool uses "RNGCryptoServiceProvider" class to generate encryption/decryption key. It can be used to generate machine key entry for web.config file. Select validation and decryption algorithm to generate machine key

Now google page insites does not give me an error and Chrome now remembers my password.
