How to decrease the QR code size #155

Closed shekarkcb closed 4 years ago

shekarkcb commented 4 years ago

I seem to have issue in getting QR code displayed, it occupies whole screen (irrespective of the screen size / terminal size). Is there any way where i can fix the size of the QR code which gets generated when google-authenticator command runs ( may be height X width in any of the files or command line argument) OS : CentOS 7.6. Terminals tried : MacOS Terminal, iTerm, Putty Tried google-authenticator -Q utf8 but this inserts lines between the QR code, sometimes this doesn't get recognized by the authenticator app.

Any pointers greatly helpful.

Thanks

You can make your terminal font smaller, temporarily, while you scan the code. I don't think it's possible to make it use fewer characters, no.

For me the utf8 is smaller than ANSI, and has no empty lines. I don't have a mac.

For me it works great with GNOME Terminal on Linux, and Putty on Windows.

Thanks for the suggestions @ThomasHabets , tried decreasing the fonts, and it worked on both mac / windows putty. Closing this thread.
