Keep it in a fire safe or safe deposit box.

Just follow the 3-2-1 backup rule. 3 copies in 2 different mediums with 1 stored off site.

Amnesia - I wound not know that I have a password manager. I wound be very screwed. No one else in family even understand what it is. I don't know what to do about it. At least they know I have a Gmail account. But I don't use it for logins. Maybe I can regain access to my domain with BankID. I have the password file on phone, server and on my workstation. So I will be fine regarding hardware failure.

bitwarden has a cool takeover option which my gf has, in case I would lose access, and vice versa.

I keep my vault password in fireproof containers in two separate off-site locations. And I use BitWarden, which has an emergency access process. I would assume many other vaults do too.

2FA backups are also stored in locations separate from where I have the vault password.

I also backup my vault a few times a year and keep those encrypted in another digital location.

Any thoughts on solutions to the problem of losing your phone

Having a backup copy of your password manager on more than one device and location.

I have mine on phone, pc and usb drives.

Single points of failure are always a problem.

either it's emergency, or OP and this post's OP have shared minds: https://lemm.ee/post/16530953

Paper backup in my sock drawer.

I have my master password written on a piece of paper in my desk drawer, but with no references to what it's for. I guess if someone broke into my house, managed to unlock my computer or my phone and also put two and two together that it's my master password, they could get in.

But if something happened to me, that password location is known to my family, and my vault has a backup 2FA to my son's phone.

In theory: regular rotated disk backups kept in a safety deposit box.

In reality: a single disk sitting in my dresser that's super out of date.

I have my keypass file synced on multiple devices locked with a strong password and a keyfile. So if I lose my phone, I still have access to my file on another device. All of my devices are encrypted too.

I have my password database synced multiple places and I use two yubikeys (one as a backup) to unlock said password database and for OTP. This protects me from losing access to anything as a result of a lost/broken device.

It doesn't help in the case of being unable to perform those functions yourself for whatever reason. Perhaps give instructions on how to access all of that to someone trusted?

Encrypt it to a thumb drive and split the password up between people you trust in envelopes.

probably something like that emergency pill that astronauts and pilots are rumored to have. I'd take one of those pills.

I have one time codes for that

Right now I export it periodically to an encrypted flash drive but I know that isn't sufficient. I run Vaultwarden and back up all my docker volumes hourly and replicate to S3 nightly.

Theoretically I should be able to recover but I need some off those passwords to do so. Ideally local caching or one of my exports should be sufficient but I haven't had time to actually test this.

HDD at work.
