Overview

Requires a gemspec to have ‘rubygems_mfa_required` metadata set.

This setting tells RubyGems that MFA (Multi-Factor Authentication) is required for accounts to be able perform privileged operations, such as (see RubyGems’ documentation for the full list of privileged operations):

  • ‘gem push`

  • ‘gem yank`

  • ‘gem owner –add/remove`

  • adding or removing owners using gem ownership page

This helps make your gem more secure, as users can be more confident that gem updates were pushed by maintainers.

Examples:

# bad
Gem::Specification.new do |spec|
  # no `rubygems_mfa_required` metadata specified
end

# good
Gem::Specification.new do |spec|
  spec.metadata = {
    'rubygems_mfa_required' => 'true'
  }
end

# good
Gem::Specification.new do |spec|
  spec.metadata['rubygems_mfa_required'] = 'true'
end

# bad
Gem::Specification.new do |spec|
  spec.metadata = {
    'rubygems_mfa_required' => 'false'
  }
end

# good
Gem::Specification.new do |spec|
  spec.metadata = {
    'rubygems_mfa_required' => 'true'
  }
end

# bad
Gem::Specification.new do |spec|
  spec.metadata['rubygems_mfa_required'] = 'false'
end

# good
Gem::Specification.new do |spec|
  spec.metadata['rubygems_mfa_required'] = 'true'
end
