Why did my SMS request go to my family member phone instead of mine?!? New Family Plan user

spamsucksass-general

My wife and I each maintained our own last-pass, but I recently upgraded to the family plan and invited her to the family. I have 2FA setup through my Lastpass Authenticator app, and use the Firefox plugin.

When I open a new browser window, it has been normal to see the prompt to authenticate. My LastPass Authenticator app usually notifies me, I go in an allow it. The plugin automatically completes the login process. I have also tested entering the time based one time password into the code box. All has been fine.

Today, I open a new new browser window but missed the window to authenticate with the app, and I was feeling lazy, so I clicked on the send SMS code button. Instead of the code going to my phone as it should, it went to my wife's.

I did add her email, NOT HER PHONE NUMBER, to my emergency recovery stuff. Other than that, her information does not exist anywhere on my account.

WHY DID IT SEND HER MY CODE?!? I have tested it a few more times and the Firefox LastPass send SMS button ALWAYS sends the code to my wifes phone.

Any ideas welcome. This shouldn't have happened with a nOOb setting things up for a Family Plan according to the onscreen guides.

Then your wife's phone number is probably under Account Settings> Multifactor Authentication> LastPass Authenticator.

You are probably using your wife's phone number in Account Recovery by SMS.

Follow these instructions to change this in your account.

When I check my setting in the instructions you sent, it shows my phone number, not my wifes....

Bingo. That got me on the right track again.

I think ... Since I never really clicked that button (Send SMS) before on the browser plugin in order to log in, usually relying on the app to authenticate, I was confused as to how it SHOULD work.

My lesson learned was when using the LP Authenticator app for 2FA, reserve pressing the "Send SMS" button when logging into LP itself unless you lose your phone or something, and need to rely on your emergency phone you entered (aka my Wife).

In order to correct my situation (if I want to change my emergency recovery phone number), I borrowed from those trying to set up authenticator onto a new device, but same phone number.

Open My Vault-->Account settings-->Multifactor options-->Disable then re-enable. This will bring up the 3-step enrollment process again if you want to re-enroll the app to the device itself, or if you want to change the emergency phone number, or both if you want.
