Please note you can only change your password if you log in to Piktochart directly. If you use Google or Facebook login to access your Piktochart account, you'll have to change that password, instead.
To change or reset your password, log out and use this link to choose a new password (click or copy & paste the link into your browser):
The response will be sent to the inbox of the email account registered to Piktochart.
You can also stay logged in, and after clicking the Profile icon in the top right, find Account Settings. You'll see a password reset option there, as well.
