What do I do if I’ve forgotten my password?

If you’ve forgotten your password for your Nest account, you can reset it online with your username, a passcode we’ll send to you and the answers to your security questions.

On the login page of the Nest website select ‘Forgotten password?’.

You’ll need to enter your username and select the option of ‘Email me a passcode’. Select ‘Next’, and we’ll send a passcode to the email address registered on your Nest account.

If you’ve forgotten your username, please see What do I do if I have forgotten my username?

You’ll now need to enter the passcode that we’ve emailed you and click 'Verify'. It’ll be valid for 10 minutes and if you don’t receive it, or if it has expired, then you can request for a new one to be sent by selecting ‘Resend passcode’.

After the passcode is verified, you’ll need to answer the security questions which are held in your online account. You can then create a new password to log in to your account.

What if I’ve been sent a passcode by post?

If we’ve sent a passcode to you by post, you’ll need to follow the same steps above, and select the option of ‘I’ve received a passcode by post’ on the forgotten password page.

Select ‘Next’ and you’ll be asked to enter your passcode, answer your security questions and create a new password.
