====== Migrating a Chrome profile to another computer ======
Cookies and passwords are encrypted with DPAPI. Boo! This makes things difficult and annoying.

See https://sourceforge.net/p/keepass/wiki/Recover%20Windows%20User%20Account%20Credentials/ and https://old.reddit.com/r/vivaldibrowser/comments/65qrlb/importing_cookiespasswords_from_vivaldichrome/

===== The simple bit: copy the actual profile data =====

  - Copy ''%LocalAppData%\Google\Chrome\User Data'' to the new computer
  - Export ''HKEY_CURRENT_USER\Software\Google\Chrome\PreferenceMACs'' using regedit
  - Delete this key on the new PC and run the file to apply it

You can stop here but only bookmarks and some other stuff will be transferred (untested)

===== The complicated bit: migrate DPAPI keys =====

  - Enable "Show hidden files [...]" **and disable "Hide protected operating system files"** in Windows Explorer if not already done
  - Copy the SID folder from ''%AppData%\Microsoft\Protect\'' to the new PC (folder called "S-1-5-21-[...]")
  - Download {{ :windows:dpapi_migration.reg |}} and edit <SID> and <username> to match the old PC account, then apply it.
  - Run ''dpapimig.exe'' in cmd/powershell and enter old password if required.
  - Done!

Now you should be able to delete the copied SID folder and open Chrome.
