A step-by-step guide to moving off Gmail in a weekend, including the part most guides skip: untangling every account that uses Google to log in, so you never get locked out.
Written by someone who has actually done this migration more than once. Honest about what works and what does not yet.
Moving your messages is the easy half. Proton's own tool handles your mail, contacts, and calendar in one pass. The half that locks people out is the rest: the bank, the password manager, the employer account, the dozens of sites that use "Sign in with Google" or send your 2FA codes to Gmail.
Pull the plug in the wrong order and you can lock yourself out of accounts you need. This guide gives you the safe order of operations and a worksheet to inventory every account before you touch anything. That section alone is worth the price.
Check your storage and inventory every account tied to your Gmail before you move anything. The step that prevents the disasters.
Move all three with Proton's Easy Switch, and keep Gmail forwarding so nothing falls through the cracks during the transition.
Get your documents out cleanly through Takeout, including the caveat about native Docs and Sheets that trips people up.
Move years of photos without scattering your albums, plus the current platform limitation and the workaround.
The differentiator. Sign in with Google, 2FA, Google Authenticator, and Chrome's password manager, handled in the right order.
Park or delete the Google account safely, only once everything that depended on it has been moved and verified.
Before you move a single email, run this one-page check. It is the audit step that saves people from locking themselves out. Free, no catch.
