Latest version - supplied option --auth-username is not supported and will be ignored

Just downloaded latest version ( and suddenly, I’m getting the auth-username not supported error. Prior to version update, everything worked fine.


  • AES 256 w/ passphrase
  • MS OneDrive v2 (no changes)
  • adv options (none)


  • re-verified the OneDrive token
  • turned AES encryption off/on
  • verified browser is not auto-populating pw’s
  • verified pw manager (1password) is not auto-populating pw’s
  • created new backup (see below)

new backup - error
The process cannot access the file because it is being used by another process.

Any suggestions?

Try the suggestion in this post:

OK, so it turns out that the id/pw was embedded in the dest url…but what I can’t figure out is why it worked in and suddenly broke in 20.6.3.

Anyway, working now. Many thanks!
