If you need to change your password for any reason this is simple to do using the following steps.
Log out of your Ember account:
Once logged out you will be taken to the login page, on here you should click the 'forgot password' button:
Once done this will ask you to pop your email in as shown below, you will then receive an email with a link for you to reset the password!
Please note: this will only work if you login using the email & password flow. If you aren't receiving an email it's likely because you usually login with the Google flow. i.e. if you usually click "Continue with Google". If you want to change this you can do this via settings > account details.
