Hello there,

according to [https://support.sonatype.com/hc/en-us/articles/115015110067-Using-User-Token-s-with-NPM](https://support.sonatype.com/hc/en-us/articles/115015110067-Using-User-Token-s-with-NPM) it should be possible to use User-Token that contain uppercase usernames, however I have not found this to be working

When trying to login i get the following:

Username: (33U7wmRv)  
npm WARN Name must be lowercase  
Username: (33U7wmRv) npm ERR! code E401  
npm ERR! Unable to authenticate, need: BASIC realm=“Sonatype Nexus Repository Manager”

The KB article suggests you should modify your npmrc file, not use login.
