I have lost my Days of Wonder password account ...

 There are several ways to retrieve a lost password:

If you remember which e-mail you used for your Days of Wonder account, simply go to the Web site and ask for a password reset at: https://www.daysofwonder.com/reset/

If you are not sure which of your e-mails you used, you can try each of them on that page until you find the one that works.

If you have a Steam account linked to your Days of Wonder account, you can connect to your Days of Wonder account using your Steam credentials on https://www.daysofwonder.com/login/ then go to your account profile at https://www.daysofwonder.com/myaccount and you will able to change your password there.

From the Ticket to Ride and Small World 2 apps, make sure you are connected to internet and press your avatar on the top right of the screen. This open the account settings page. You'll see there the days of wonder account and eventually the play store details you are using to play. . Then press the "Send me my password" link. If there was no e-mail in your account (which often happens if you created your account through Steam or Game Center), you will have the opportunity to enter it to update your account at the same time.

If everything fails, you can contact us and we will search your account. Please understand that we don't have a crystal ball, so you will need to give us some pieces of information to find your account. We also ask you to try all the procedures described above before contacting us.

I am connected but I forgot my password. How can I get it?

For instance in Ticket to Ride, make sure you are connected to internet and press your avatar on the top right of the screen. This open the account settings page. You'll see there the days of wonder account and eventually the play store details you are using to play.
