Re: rtfm - password logging
I usually make up the password in an email draft that is not normally sent. Note that is on a local POP3 account, so no IMAP replication, and not sent unless it is a convenience account (such as discussion fora like this one).
That is for private use nowadays since I retired a couple years ago. When I was working, I would put it in my phone's "Notes" section for my own contact info in some cases, or a post-it that I kept around my desk at home as I worked from there 90% of the time my last 10 years or so. Considering how many post-it scraps littered up my home "work" desk with my random filing system of paper piles, it was fairly safe in obscurity mode as it was scruffy looking with no mention of which password it was...
