View All on GitHub Resident credentials are silently overwritten along user.id prefix chain (raspi_1 → raspi_12 → raspi_123) on v7.0 3 months ago
AI Summary: On pico-fido v7.0, resident credentials are being silently overwritten when their user IDs share a common prefix. This occurs because the system incorrectly deduplicates credentials based on a prefix of the user ID, leading to data loss. For example, registering 'raspi_12' overwrites 'raspi_1', and 'raspi_123' overwrites 'raspi_12'.
