"Warning: Cryptocurrency Theft Involving Kaspersky Password Manager - My Story"

[satscraper]

~

Very sad story and I understand your feelings towards  Kaspersky team members who  you have blamed of being involved into the  stealing of your SEED. As has been said by others the use of any software  to keep SEED is a bad practice. However there might have  been on your machine a malware which has stolen   your SEED by some way. Why don't consider such development?

Storing your private keys (aka seedphrase) in a password manager is no less safe then storing all your sensitive passwords in a password manager, IMO.
For some it might be safer to use a PM then keeping a physical copy in their house where it could be lost or stolen.

Millions of bitcoins have been lost forever because people lose the physical copy of their seedphrase.
So it might be argued that storing a physical copy of it somewhere  is no less risky then storing it online.

But if you do decide to store it online make sure to make use of Bitcoin's hidden wallet feature.
So even if someone steals your private key they will never be able to access your wallet without knowing your secret passphrase to open the hidden wallet.
Obviously, don't ever store your passphrase with your seed phrase. And make sure you don't ever forget your passphrase because without it
you will never be able too access your wallet with the seedphrase alone. Ideally your passphrase should be stored only in your head.

For those who don't know a hidden wallet, also known as a 25th word, is simply a wallet that is accessed with a passphrase that you make up to access your wallet.
Many hardware wallets such as Trezor and Coldcard offer this feature. It is a wallet within a wallet.

Hidden wallets are a great security feature that everyone should learn how to use IMO.
