Earthdata Login has recently added functionality so that users can generate  User tokens for themselves via the EDL GUI or the API.  User tokens are valid for a duration of 90 days.  Users can generate these tokens and use them with compatible applications during the application authorization process.  A user is allowed a maximum of two valid user tokens at any given time.  If you already have two valid user tokens, and wish to generate a new token  please delete  and existing token and generate a new one.  


Generating a User token from EDL GUI
