Extracting 2FA codes from the abandoned ‘Authenticator Plus’ (ios)

This article provides a step-by-step technical tutorial for recovering two-factor authentication (2FA) keys from the discontinued 'Authenticator Plus' iOS app. It details how to extract the encrypted database from an iPhone, decrypt it using SQLCipher with a specific PRAGMA configuration, and generate OTP URIs. The guide then shows how to create a local Ruby script to safely generate QR codes from these URIs for migration to a new authenticator app, emphasizing security by avoiding online tools.
