2-factor does not work after exchange of phone

[Jesper E. Siig]

I have been using Google Authenticator for 2-factor authentication for my Atlassian account.

I did take a backup of my old phone and restored it on the new one, but it seems Google Authenticator has forgotten me and wants me to set up a new account.

How do I get a new QR code or configuration key?

I can log into my Atlassian account with a recovery key.

BR,

I believe this is more Google Authenticator related, not Atlassian related question.

 But here are some solutions from Google itself.

1. On your new phone, install the Google Authenticator app.
2. In the Google Authenticator app, tap Get Started.
3. At the bottom, tap Import existing accounts?
4. On your old phone, create a QR code: In the Authenticator app, tap More. Transfer accounts. Export accounts. ...
5. On your new phone, tap Scan QR code.

How do I transfer my Google Authenticator if I lost my old phone?

If you've lost access to your primary phone, you can verify it's you with: 

• Another phone signed in to your Google Account. 
• Another phone number you've added in the 2-Step Verification section of your Google Account. 
• A backup code you previously saved.
