All checks were successful
ci/woodpecker/push/default Pipeline was successful
Viktor's passkeys all vanished and he was suddenly being asked to log in
multiple times a day instead of ~monthly. Root cause: on 2026-06-18 an ad-hoc
tripit passkey E2E test (run from the devvm as akadmin via python-httpx) cleaned
up "the demo user's" passkeys with GET /core/users/?search={demo} then DELETE
each device of users[0] — but the fuzzy search returned the REAL account, so it
wiped all 6 real passkeys. Losing passkeys forced fallback to Google login, and
the social-login stage (default-source-authentication-login) had the provider
default session_duration=seconds=0, which falls back to UNAUTHENTICATED_AGE=2h —
hence the constant re-logins. (Password + passkey logins were already weeks=4.)
Changes:
- authentik: adopt default-source-authentication-login into Terraform (import)
and pin session_duration=weeks=4, so Google/GitHub/Facebook logins last as long
as password/passkey. Immediate relief without re-enrolling.
- authentik: document the provider-schema gotcha — authentik_stage_identification
exposes no webauthn_stage / enable_remember_me attribute, so they must NOT be in
