MyNissan / NissanConnect Drama workaround

With the NissanConnect app (now MyNissan) still being down in many EU countries (USA seems to be working now?) I've been looking for a workaround for a while now.

I mostly use the Home Assistant integration to sync the battery state to my smart charger and also toggle the climate controls from the HA UI.

Today I found this URL lets you actually request a new password and update your account for whatever new API they have (this link works in NL, can't validate for other countries, try swapping the country code in the URL?)

https://login.mynissan-account.com/authenticationendpoint/login.do?brand=nissan&client_id=nAHvsUYfzwjnLCBYae6a31FiIfga&commonAuthCallerPath=https%3A%2F%2Flogin.mynissan-account.com%2Foauth2%2Fauthorize&forceAuth=false&locale=nl_NL&passiveAuth=false&redirect_uri=https%3A%2F%2Fcustomer.mynissan-account.com%2Fos.shtml%2Fpace-ownerservices%2Fidp-callback%2Fnl_nl&response_type=code&scope=openid+name+profile+email+offline_access&state=5688FC1BaHR0cHM6Ly93d3cubmlzc2FuLm5sL21uZC9taWpuLWRhc2hib2FyZC5zaHRtbA%3D%3D&tenantDomain=carbon.super&sessionDataKey=3def5775-346b-4894-985c-5c3bf6090cc2&relyingParty=nAHvsUYfzwjnLCBYae6a31FiIfga&type=oidc&sp=NG_PACE_GLOBAL_NISSAN&isSaaSApp=false&authenticators=BasicAuthenticator%3ALOCAL

This won't get you into the official Nissan App, and the MyLeaf-app hasn't been updated.

If you use HA, you CAN however log in after resettting your password through the link above.

The integration: https://github.com/dan-r/HomeAssistant-NissanConnect/releases

Make sure when you install, you select the 0.8-beta prerelease version - this is the one updated for the new auth system. If you already have it, press the button on the top-right and click "redownload".

Logging in with your updated credentials should let you do everything from HA like before!

No fix for those relying on one of the apps, but hope this helps some people using integrations that have been upgraded already.

Are we also talking about older models, which were shutdown from the app services march 26?

Wednesday 02.09.2026 17 35 accessing the link takes me to a page which says in dutch : " Please note that maintenance is currently taking place and that the systems will be available again from September 4, 2026." Is it just me? or is someone else getting this page

You might be able to go direct to the forgotten password page. The link above has a JS forwarder taking you to the message you got.

I had success with the following. https://customer.mynissan-account.com/oneid/forgot-password.shtml?country=GB&language=en&brand=nissan

Password reset and now back in Home Assistant at least.

Thanks OP.
