So both phones are registered for 2FA. I got the account transferred to the new phone by deleting the MS Authenticator app, reinstalling and restoring from the old phone backup. When I go to use the Authenticator app to log in, it wants me to choose which phone to send the code. If I send it to the new phone it won’t accept it. If I choose the old phone it accepts it. Here’s the thing…the code is the same in the Authenticator app on both phones, but only accepts if I choose the old phone.

Tesla App multi-factor authentication
- Thread starter Randy-12
- Start date
I logged into my Tesla acct. online and there’s no option to disable 2FA. The only thing it allows you to do is manage MFA by either renaming or removing registered devices, or managing your backup codes.
I tried setting up Authy but to add an account it wants to scan a QR code or enter one manually (basically the same thing), which you can’t do once MFA is initiated on your account.
Have you read the support page on 2FA
Multi-Factor Authentication | Tesla Support Canada
Multi-factor authentication protects your Tesla Account by requiring a secondary form of verification before signing in. Once multi-factor authentication is set up, you’ll be required to enter your account credentials and verify your identity from a registered device each time you sign in.

I see this is an older thread, yet a recent issue arose with my friend who could not login to his account, or the app and he ran to me for help. It looks like several folks here understand the 2FA process, but some may not.
So, this is a bit of a heads-up to people that use the two-factor login, specifically the "Authenticator". He was completely locked out of his account and of course could not login to the app either. He was using an authenticator. The problem was that even though the Tesla account recognized his login name and password, when it asked for the authenticator code, Tesla would indicate the code from his authenticator was not correct.
Here is what he did not realize: He upgraded his smart phone. When this happens, even though you may create a backup of all the apps and even if directly doing a Bluetooth transfer from phone to phone, the authenticator is tied to a specific device, so code generation capabilities become broken. An app that uses the authenticator will no longer allow a login. So, it is not just an issue with the Tesla login.
He ran down to the service center which I told him was a waste of time as they won't be able to help. When he came back, I gave him the 888 number to call. I listened in as a very nice, super helpful guy came on the phone (after a 15-minute wait in line on the call). They asked some security questions to verify his identity and then sent him a link to disable the 2FA so he could get back into his account and app. I was impressed for a change that he got help so quickly and easily.
In my opinion, Tesla could do a better job with login process. When this happens at other institutions like banks that allow you to use 2FA, there is a way to send either an email or a text code to temporarily disable 2FA so you can get back in. Tesla currently does not have that.

You can and should setup the Authenticator on multiple devices. I have it setup on my iPhone and iPad.

Yup that is what I told him, but he is like 200 years old and didn't understand
EDIT. I guess I should have said he has only ONE device.

I guess getting the backup codes was also too hard. Oh well, what can you do?Yup that is what I told him, but he is like 200 years old and didn't understand

How often and when are you asked for the multifactor authentication code? Do you have to use it every time you use the Tesla app? Can you still use third-party apps like Tessie? I don’t have to deal with it every single time I use an app just wondering before I commit to using two factor authentication, thanks for the help

Only need to use it when signing into the app for the first time, after that it keeps you logged in. It does make you use it every time you sign into Tesla.com (web). It would also be required for any 3rd party apps, but you should be able to check to see if MFA is supported before turning it on.

Do you set up the backup passcodes ahead of time, that is, when you have access to your account?

During the MFA setup you are given the option of downloading a set of backup passcodes, which you should do. You should also setup MFA on two devices such as your iPad and iPhone.
