Answering your questions about adding passkeys and MFA to your existing app
Absolutely. This is the recommended approach. Start with internal users, beta testers, or a percentage of your user base. Authsignal's rules engine lets you target specific user segments, email domains, or geographic regions. Monitor adoption and user feedback before expanding.
No. Authsignal integrates with your existing user database and authentication flow. Users keep their current credentials while you layer in passkeys and MFA. There's no forced migration, no data export/import, and no changes to your identity provider setup.
Most teams have a working integration in 1-3 days. The fastest path is using our pre-built UI components and SDKs. For custom implementations or complex workflows, plan for 1-2 weeks. The timeline depends on where you want to add authentication (login, checkout, admin panel, etc.) and your testing requirements.
Nothing changes for them. Authsignal supports progressive enhancement. Users can continue with their existing authentication methods (passwords + optional MFA) while others adopt passkeys. You control the rollout strategy and can offer passkeys as an optional upgrade or gradual default.
