+### Improvements to `My Account > Lost password` endpoint
+
+https://github.com/woocommerce/woocommerce/pull/27898
+
+The `Lost Password` endpoint has two changes allowing it to be used in the create account flow in the new checkout block in WooCommerce Blocks.
+
+1. The page title can now be overridden, via an `action` url parameter.
+2. The lost password reset form can now be used even if the user is logged in (previously required logged-out user).
+
+#### Test normal "forgot password" flow
+1. In an incognito window, visit `my-account/` and click `Lost your password?`?
+2. Enter a username or email for a user account and click `Reset password`.
+3. Open the reset password email and click the `Click here to reset your password` link.
+4. Enter a new password and log in to the account to confirm password change success.
+
+This flow should work the same with the changes.
+
+In addition, in step 3-4 you can now reset the password in a logged-in browser session. The password reset should not be possible if the logged-in user not the user that triggered the password reset.
+
+#### Test custom `Set password` title
+This flow will be used for setting a password in new accounts. The [relevant changes in WooCommerce Blocks](https://github.com/woocommerce/woocommerce-gutenberg-products-block/pull/3236) haven't been released yet.
+
+You can simulate this part of the flow by setting an `action=` URL param in the above reset flow.
+
+1. In an incognito window, visit `my-account/` and click `Lost your password?`?
+2. Enter a username or email for a user account and click `Reset password`.
+3. Open the reset password email and click the `Click here to reset your password` link.
+4. Edit the url and set the action param to `newaccount`, for example `http://teststore.com/my-account/lost-password/?show-reset-form=true&action=newaccount`. Reload the page.
+5. Page title and navigation breadcrumb should now show `Set password`.
+6. Enter a new password and log in to the account to confirm password change success.
