No. If your browser hasn’t prompted you to remember your username and
password you need to tell it to do this: 

• Internet Explorer:  go to Tools/Internet
  options/content/ auto complete settings/ tick “prompt me to save
  passwords”
• Firefox:
  Preferences/security/remember passwords for sites
• Safari:
  Preferences/Autofill/tick “user names and passwords”

You should then get the “remember this password?” prompt when you
access the site. Click “yes”.

In the future you will only have to type the first letter of your
username and the full username should appear. You click on this and the
password will be entered automatically.
