| Description |
|
If dark is the default theme, the QR-Code for TOTP verification is white on black. No TOTP Authenticators works in this case. |

Please elaborate what you see / some error / empty screen? |

What I see is ok, but if the QR-Code is white on black, no authenticator apps works. Nothing happened. If I switch to a bright theme (QR Code black on white) it works. Tested it with MS Authenticator and FreeOTP |

That is strange, I tested both dark themes, and MS Authenticator works fine! Are you able to read these samples? |

Same here, my app can read these codes regardless of colors. But the number of sources suggest that some phones (or, perhaps, some barcode scan libraries) have problems with inverted QRs. Let's make it always black on white. |

Looks like after the fix, if using MFA with dark background Google Authenticator on Android phones do not recognise the QR code. On iPhone it did fine. |
