Blink authorization failed

Error message

Blink authorization failed

What it means

In blink camera.async_enable_motion_detection, an UnauthorizedError from camera.async_arm(True) triggers async_start_reauth on the config entry and raises ConfigEntryAuthFailed('Blink authorization failed'). The stored Blink token was rejected, so the motion-enable command cannot proceed and HA switches the entry to reauth-pending.

Solutions

  1. Follow the reauth prompt for the Blink integration entry.
  2. Remove and reconfigure the Blink integration if reauth loops.
  3. Confirm credentials work in the Blink app.
  4. Update Home Assistant core for current blinkpy auth support.
Defensive patterns

Strategy: try-catch

Try / catch

from homeassistant.exceptions import ConfigEntryAuthFailed

try:
    await camera.async_enable_motion_detection()
except ConfigEntryAuthFailed:
    notify_user("Blink session expired — complete reauth")

Prevention

When it happens

Trigger: Enabling motion detection with an expired/revoked Blink token — password changed, session revoked, or Blink auth API changes not handled by the installed blinkpy version.

Common situations: Aged token on a long-running instance; password rotation; multiple active sessions causing revocation; outdated HA core / blinkpy.
