Documented steps
Authenticate as an owner of the package or a member of the team that owns its scope.
Run: npm access set mfa=<mode> <package-spec> where mode is none, publish, or automation.
Use publish to force a one-time password from every publisher on each publish attempt; use automation to permit approved long-lived tokens without interactive otp.
If your account has 2FA enabled, supply the code via the otp option to complete the setting.
Verify: attempt a publish from an account without 2FA and confirm it is rejected, or check the package's access status.

Known gotchas
publish mode rejects any publish that does not carry a valid second factor, which can break naive CI pipelines that publish without otp.
automation mode is the escape hatch for non-interactive automation: it allows machine tokens while still protecting the account.
Scoped packages need owner/team-of-scope privileges to change this setting.
You still need a valid otp from your own account to apply the setting if your account is 2FA-protected.
