Re-authenticating (2.2.5 – Level AAA)

Save user data when re-authenticating.

Introduction

It may be essential for users to re-authenticate their identity for certain functions. For example, you might set a login to expire after a certain amount of time in case a user leaves their computer unattended.

Some users need longer than others to complete tasks on a website. You can help these users by saving the information they enter and when they re-authenticate (such as logging back in), displaying the same data.

How to Pass ‘Re-authenticating’

When you ask a user to re-authenticate their identity, ensure the user can continue exactly as before with saved data (for example, their shopping basket contents, input into forms or accessibility options).

‘Re-authenticating’ Tips

Ensure surveys and questionnaires can be saved part-completed and finished later.

If you ask your users to re-authenticate after a certain amount of time, consider whether your use of a time limit is justified under Timing Adjustable and No Timing. If the limit is for security reasons, such as protecting user data, this will pass both guidelines.
