You don’t need a special “anti-detect” 2FA app—any well-built TOTP generator that lives on your desktop (or in your browser) will work alongside Safari or Chrome profiles. If you want a standalone app, Authy’s desktop client is rock-solid: it encrypts your tokens in the cloud, lets you pin separate vaults for different profiles, and pops up in your menu bar so you never miss a code. For a more lightweight, local-only solution on Windows, WinAuth is a good choice—portable, open-source, and stores everything in an encrypted file you control.
