-      <p class="govuk-body-l">As part of upcoming work to offer new tools and services, all Analytical Platform will need to authenticate with their Justice identity so that we can store your @justice.gov.uk email address.</p>
-      <p class="govuk-body">You will need to complete authentication by 30th April 2024. If you do not currently have a @justice.gov.uk email address, <a href="#" class="govuk-link">see our guidance on requesting one.</a></p>
+      <p class="govuk-body-l">We're planning some changes to how you log into the Analytical Platform. We are transitioning from using GitHub to Microsoft 365 (i.e. your @justice.gov.uk email address & password). </p>
+      <p class="govuk-body">For now all you need to do is click the button below to authenticate via Microsoft 365. This is a one-time operation which will link your current Analytical Platform account information to your @justice.gov.uk email address. This means you'll keep all your current permissions, and there's nothing extra you need to do.</p>
+      <p class="govuk-body">You will then continue to log in to the Control Panel via your GitHub account as usual. You can read further information about these changes in the <a href="https://mojdt.slack.com/archives/C4PF7QAJZ/p1712592546423129">#analytical-platform-support</a> Slack channel.</p>
