Try again and check the following:

Why do I have to give my email address?

Giving us your email address lets you do the following things:

  • Reset your password if you’ve forgotten it
  • Recover your account if it’s been locked

We will not email you unnecessarily or give your email address to other parties. It is important that you give us a correct working email address as we will check it during registration by emailing you and asking you to reply.

What does the option ‘Remember me on this computer’ mean?

If you tick the "Remember me on this computer" box when signing in or registering, the computer you are using at the time will remember you and automatically sign you in if you visit the Hydration Hub again. This means you don’t have to type your username and password each time you visit.

Never tick "Remember me on this computer" if you are using a public computer, for example in an internet cafe or at a library where lots of people share it. To keep your account safe, only tick this box if you are the only person using this computer.
