Security Key Patterns
Originally published in 2022 (prior to passkeys) these patterns provide user experience (UX) guidelines and best practices for relying parties and implementers seeking to enable multi-factor authentication (MFA) with FIDO security keys as a second factor, based on a regulated industry (for example, banking, or healthcare) use case.
These guidelines aim to accelerate decision-making during FIDO implementation and specify what information and controls should be given to users. Note that these UX recommendations are optimized for browser-based sites, accessed on desktop/laptop computers, rather than mobile apps or mobile web. The guidelines do not, however, include recommendations about security policies or account recovery.
