npm login can fail when stored npm credentials and the account password format are out of sync, resulting in the password_sha and pbkdf2 mismatch message.

may not mix password_sha and pbkdf2authentication

Observed message

may not mix password_sha and pbkdf2

Why it happens

  • Stored npm login credentials are stale or inconsistent with the current account password state.
  • Local npmrc authentication fields conflict with current registry login expectations.
  • The npm account password metadata has not been refreshed for the local client.

How to fix it

  1. Log in to npm on the website and confirm the account email is correct.
  2. Change the npm account password, even if reusing the same value.
  3. Clear registry login fields from ~/.npmrc and run npm login again.
