Yes, when you upload students into Educake, you will have the option to send students emails with their usernames and reset password links. You'll be able to choose whether you send this to new students only, students who already have accounts, or both. You must provide email addresses for students on your spreadsheet in order for the emails to send.
Here's what one of these emails looks like:
Your teacher has created an Educake account for you or asked us to send you your login details. You can log in at www.educake.co.uk with your username and password.
Your username is: rosad0001
If you don’t know your password or forgot what it is, you can set a new one here:
