Short answer: Evidence item 4.5.6 is a new mandatory requirement for Category 2 IT suppliers under DSPT 2026-27. It requires that software you supply to health and care organisations supports multi-factor authentication (MFA) or identity federation to industry standards or, if it doesn't yet, that you have an approved, realistic, resourced plan to get there by 30 June 2027. It's one of five changed evidence items for Category 2 this cycle, and the only one with its own hard deadline written into the requirement text.
NHS England's evidence text for 4.5.6 reads: "Software provided to health and care supports identity federation or multi-factor authentication to industry standards, or you have an approved, realistic and resourced plan to achieve this not later than 30 Jun 2027."
Two things are worth separating immediately, because they get confused:
4.5.6 is about the software and products you supply to the NHS; does the product itself support MFA or identity federation for the people who use it?
4.5.3, an existing (and also updated) requirement, is about MFA on your own organisation's remotely accessible and privileged accounts, your internal IT, not your product.
You need both. A supplier with excellent internal MFA but a product with no MFA support hasn't met 4.5.6, and vice versa.
There are two routes to evidencing 4.5.6:
A plan that's aspirational rather than resourced is unlikely to survive independent audit scrutiny, particularly since 4.5.6 sits inside the 102 mandatory Category 2 evidence items and your submission is independently audited, not self-assessed.
Most DSPT evidence items are assessed against your current state at submission. 4.5.6 is unusual in writing a specific future date, 30th June 2027, into the evidence text itself, rather than relying on the toolkit's general annual deadline. That's a signal NHS England is treating supplier-side identity controls as a priority it wants locked in, not just evidenced as "in progress" indefinitely.
If your product roadmap doesn't currently include MFA or identity federation work, it's worth raising this with your product and engineering leads now rather than at submission time. Authentication and identity work, especially identity federation against standards like SAML or OIDC, routinely takes longer to design, test and roll out than teams initially expect, particularly across an existing customer base.
4.5.6 is one of five evidence changes for Category 2 this year, alongside the new Software Security Code of Practice requirement (9.5.11), the updated Supply Chain Charter item (9.5.10), the new Products and Services data collection, and two dropped requirements.
