Otp.NET
A .NET implementation of TOTP and HOTP for things like two-factor authentication codes. (by kspearrin)
extract_otp_secrets
Extract one time password (OTP) secrets from QR codes exported by two-factor authentication (2FA) apps such as "Google Authenticator". The exported QR codes from authentication apps can be captured by camera, read from images, or read from text files. The secrets can be exported to JSON or CSV, or printed as QR codes to console.

Google Authenticator uses TOTP or HOTP, not really sure how those work (after all that is job for you), but I would try to use https://github.com/kspearrin/Otp.NET

how to transfer all my 2FA codes from google authenticator to authy
Getting the code out of Google Authenticator is not trival. If you are good with python, someone has written a script to do that https://scito.ch/content/extract-secret-keys-google-authenticator-qr-export. However, with 17, you may be better off just doing it manually.

Ask HN: Why is today's Internet experience so user hostile?
I was able to take a screenshot of GAuth backups on iPhone using the button hotkeys(IE: Power+Volume up). I setup a container that runs a go version of GAuth and used a python script to decrypt the (decrypted QR code) backup keys. Then I backed up the encrypted keyfile to offline disk, encrypted the container backup and deleted it from the hypervisor.
