I've created a password reminder and record-keeper for you to record and store your passwords and account numbers, and I've attached it here for you to use. If you do use it, please make sure that you store your record somewhere safe! To help out your executor, you might consider keeping a copy of it with your will, which I assume you're storing in a safe place such as a safe deposit box. A kitchen drawer doesn't count as a safe place, as it won't protect your documents from fire, water damage, theft, small children with jam hands, or nosy people.
The password reminder is set up in sections so that you can group similar items together. You might have to add more sections though I've tried to include everything. If I've missed something, leave me a comment to let me know, and I'll add it. If you find that some of the sections don't apply to you, just delete them.
