Blink integration fails at Authentication

[Saadian]

The problem

Trying to add blink to the system, which fails at the 2fa section. I made multiple attempts with the same and different codes. As there is no way to disable 2fa, even temporarily, I cannot progress through the setup.

What version of Home Assistant Core has the issue?

core-2026.7.2

I have bumped into the same Invalid Authentication issue with Blink integration.

(Docker container) HA Core / Frontend: 2026.7.2. / 20260624.5

[vaderag]

My blink went offline in the last 24 hours with oauth error
Suspect related

[craigusus]

Broken here too

[nbastars99]

same here, seems to be another amazon auth change...

[Davidfb78]

The same thing happens to me since today

[KPics-HA]

Same here too

[donster22]

broken again. "unexpected error" upon sign in attempt to integration. was working yesterday prior to core update to 2026.7.2. rolled core back to 2026.7.1 but still broken.

Surely Blink will keep breaking this. The Home Assistant integration is the reason i don’t need to pay for a subscription.

[mrmarcog]

Same here

[LordTarly]

Same issue, integration not working

[TH1x11]

Same here.

I'm also having issues but I am not even getting to the 2fa part. I had my blink integration working for a while now but all of a sudden about 3 or 4 hours ago it stopped working. I get these errors in the logs:

I was getting Claude to help me diagnose this and came across this:

I ran the actual request instead of continuing to speculate, and the result changes the diagnosis significantly.

I replicated blinkpy's exact oauth_authorize_request() call — same params, same headers, same PKCE challenge, a random hardware_id — against the real api.oauth.blink.com/oauth/v2/authorize endpoint just now:

STATUS: 200
BODY: ...<title>Sign In - Blink</title>...
It succeeded. Blink's server accepted this exact request shape and returned a real sign-in page. That's a problem for the "blinkpy is sending something Blink now rejects" theory — if that were true, my request should have failed too, using the identical, unmodified logic.

That points somewhere different: this looks less like "the request format needs updating" and more like an intermittent availability/rate-limiting issue — plausibly Cloudflare (which fronts this endpoint, visible in the response headers) throttling or flagging traffic from specific IPs/regions, or the sheer volume of retries from thousands of simultaneously-affected HA instances worldwide (the coordinator retries every 5–40s, compounding across everyone hitting this at once) overloading the signin backend specifically, even though the endpoint works fine for a single clean request like mine.

Though I don't know how reliable that is. For some reason though, my blink integration for home assistant OS just randomly stopped working. My blink clip downloader app still works but I have a feeling once the session or token expires, I'll be in the same boat. I tried uninstalling and re-installing blink integration but I got the same thing.

I forced update from default 0.25.6 to blinkpy==0.25.7, but still the Unexpected error fetching blink data eror
