Crowdin automatically creates an account for you in the system. 

If you’re using your own username/password for Crowdin, you won’t be able to access the project. Here’s how to log in correctly to access your BLEND translation projects:

• Before opening a Crowdin project, please visit Crowdin and make sure you’re logged out, as shown below (click ‘Log Out’):

• By clicking the ‘workbench’ button on the Project page in the BLEND platform, the system will automatically log you into Crowdin through your BLEND account. This means that you don’t have to create or log in to your own personal account.

If this doesn’t work, try clearing your cache or using a different web browser.
