If you forget your password, you can reset it via email from the main login page. Click 'Forgot your password?'. You'll need to enter your email address for the reset email to send to, then click Submit.

You should then receive an email which contains a link to click to change your password. You'll need to type your new password twice, then click Change my password. The link expires in 6 hours.

You can update your password in the settings. To reach your settings, click on the button with three white dots on the top navigation bar, and clicking Settings.

In the 'General' tab, scroll down and click Change password. Enter your new password twice, and click Save changes.
