I have copied all the 2FA strings in a separate keypass database, with a different password, only in my memory. I also went through writing a simple javascript page to import all those keys to Google Authenticator via totp:// protocol. It takes a csv of all strings, and spits out the html links with totp://protocol. All using local storage only. So whenever I change phone, I paste the csv from keypass to google keep (pretty safe), open it on the new phone, copy it & paste into my html5 app, and click each link and it auto adds itself to Google Authenticator. Then I select all text in Google Keep and delete it.
