Action required: Updates to required 3D Secure data fields

[stephen-hill-safe-uk]

We recently received an email with the following subject "Action required: Updates to required 3D Secure data fields". However, the email is not very clear about what fields are required. It says the following:

The following five fields will become required:
1 Only for browser-based transactions
2 At least one phone number (work, home or mobile) must be provided
3 Merchants are recommended to pass the Cardholder Phone Number and Cardholder Email Address fields for authentication, but merchants will be compliant if they only pass one of the two fields
4 Only for SDK transactions

That is pretty meaningless information, and it not 5 fields.

The end of the email links to this Github repository to get more information, but I could not find any.

Could someone please explain clearly what 5 fields are now mandatory?

Many Thanks
Stephen
