No, QR codes are time sensitive and specific only while presented on-screen. In addition, whichever QR code you most recently used overrides all other previously used QR codes.
For example, if you began using authenticator app with Google Authenticator, but later decide to switch to using Microsoft Authenticator, the Google Authenticator will no longer work.
Using multiple authenticator apps:
If you add an additional authenticator application with a new QR code, the same QR code must be used with all authenticator apps and setup at the same time. If you do not update your QR code with each individual authenticator app you use, you will receive an invalid code error message when you attempt to authenticate at login. To setup a new authenticator app or to use multiple authenticator apps for your account, follow the below instructions:
- Login to Home Banking
- Click Edit under Security Options
- Toggle-off the by Authenticator bar, enter your password and click Save.
- Repeat steps 2-3. Then, toggle-on the Authenticator bar, enter your password and click Save.
- A QR code and 18 digit code will appear. Now use this QR code with all authenticator apps that you would like to use.
