I live in fear of forgetting my Google password (although I have several locations where my backup codes are stored) so I broke it into several parts and stored them with innocuous sounding names like "sister's birthday" and "plumber's contact info", but using a poem I know well as the phrase key. The times I've needed to refresh my memory it was very easy for me to retrieve it.
