Blink authorization failed

Error message

Blink authorization failed

What it means

blink alarm_control_panel.async_alarm_disarm catches UnauthorizedError from sync.async_arm(False), calls config_entry.async_start_reauth to kick off reauthentication, and raises ConfigEntryAuthFailed('Blink authorization failed'). This tells Home Assistant the OAuth/login token is invalid so the entry enters the reauth flow instead of retrying pointlessly.

Solutions

  1. Open Home Assistant > Settings > Devices & Services and complete the Blink reauthentication prompt that appears.
  2. If reauth loops, delete the Blink integration entry and set it up again.
  3. Confirm the Blink credentials still work in the official Blink app first.
  4. Update the blinkpy library / HA core in case auth handling changed.
Defensive patterns

Strategy: try-catch

Try / catch

from homeassistant.exceptions import ConfigEntryAuthFailed

try:
    await alarm.async_alarm_disarm(code)
except ConfigEntryAuthFailed:
    notify_user("Blink session expired — complete reauth in Settings > Devices & Services")

Prevention

When it happens

Trigger: Disarming when Blink rejects the stored credentials: token expired and could not be auto-refreshed, password changed, token revoked by logging in elsewhere, or Blink changed auth requirements.

Common situations: Long-running HA instance whose Blink session token aged out; user changed their Blink password; Blink enforcing re-login after security changes; too many devices using the same account.
