I hope someone finds it useful. https://lifehacker.com/organize-your-familys-essential-information-in-case-of-264969 https://lifehacker.com/organize-your-familys-essential-infor... and what my family should know incase if something happen to me. https://ussvicb.org/documents/What%20My%20Family%20Should%20Know%20-%20fillable.doc https://ussvicb.org/documents/What%20My%20Family%20Should%20... Somethings like the above. I've added more info such as 2FA etc in a separate sheet and saved all QR Codes for all the 2FA in my Authenticator apps, and printed them and kept two copies of it in two different locations known to family members. Updates are added as additional sheets to the binder as new codes are added and as a practice, one full dump around a 6 months to 8 months is also added. You never know what emergency might come in.
