Hi, great script! really helpful.
Not a major issue but I am having issues when trying to save to file

`prompt: saveToFile:  y
prompt: filename:  lee.json
lee.json
true
Saving to "lee.json"...
node:internal/readline/emitKeypressEvents:71
            throw err;
            ^

TypeError: saveToFile is not a function

Be nice since most desktops don't have a camera

This could be turned into a static website, if the dependencies (protobufjs) allow for it.
The prompt and colors are only needed in the CLI.

Hi !
Thanks for sharing, I wrote a simple and dirty pythonic PoC from your work

I used zbar

For macos

brew install zbar

How to use

I was just testing the code when i stumbled upon an 'error'.
It occurs whenever i try to run 'npm run start' or 'npm run start:qrcode'

npm and Nodejs are installed. and the index.js file exists in the stated location...

Am i doing something wrong/missing something, or what could be the problem here?

Having the app freely available to anyone on your computer is a security hazard

Google now use a single QR code to store all the keys you've chosen to export, so it is now not available.

Might be worth mentioning in the REAMDE that the QR code presented by Google Auth must not be more than one.

In case it is more than one the workaround is to limit the amount of exported accounts

A user can upload/select a jpg, and we then read QR and get the URI from it.
I know this can be done in python, but the aim is to run 100% client side to be compatible with #1.

An even more viable option is to implement #1, then use the webcamera from the browser to read the Google Authenticator QR code. This simplifies the process a lot.

Also found an issue with generating QRCodes due to non-escaped characters.
e.g.for windows /:*?"<>|
I often find these are used in the authenticator name

I changed lines 91-94 of index.js to the below (probably a MUCH better way of doing it than this,but it worked for me (windows) today ;-)

const Escname = name.replace(/[\\\/:*?"<>|]/g, "\-")

    const url = `otpauth://totp/${encodeURI(name)}?secret=${encodeURI(secret)}&issuer=${encodeURI(issuer)}`
    const file = `${directory}/${issuer || "No issuer"} (${escname}).png`
