Strategies
SimpleMfa supports multiple second factor mechanisms, internally named strategies. Each strategy has a unique name/slug, which is stored in the type field of a stored strategy.
SimpleMfa has some built-in strategies, but you can also bring your own. API Docs for these strategies are not available at this time.
- One Time Password (Authenticator App)
- Magic Link
- Recovery Codes
Each built-in strategy can be manually imported from @potluri/simple-mfa/strategy/{strategy}.js.
As mentioned in the integration guide, if you want to use the default strategies, you can call defaultStrategies() from @potluri/simple-mfa/default-strategies.js.
You can also override a specific default strategy by passing it to the function (for example, to override default options, or to use your own implementation):
import {MagicLinkStrategy} from '@potluri/simple-mfa/strategy/magic-link.js';
import {defaultStrategies} from '@potluri/simple-mfa/default-strategies.js';
export const strategies = defaultStrategies({
[MagicLinkStrategy.type]: new MagicLinkStrategy({
create: () => '', // Implementation omitted for brevity
validate: () => false, // Implementation omitted for brevity
});
})
