I am wondering what I should do with my passwords.
I have divided the accounts by importance into two groups:
a) the first one which are accounts like this one I am writing from. I have set them to write some post in forums. Basically, I do not care about them. Each is different. Where I could close the account I did, but I am using some of such accounts in order to use functionality I need, for example be accessible in a forum. I store them in one file which is encrypted on my external disk, actually I have two such disks, in two cities encrypted by VeraCrypt. I think this is sufficient since I can't remember such a passwords etc.
b) the other set is more important, I would not mention what kind of accounts they are, but they are important for me. Recently I have changed all passwords for good ones, consisting of a sufficient number of characters and different types of them. Each account has a different password to prevent reuse one of my password in a different account. Actually, I did memorize them, but I am worried that one day I can just forget one of the passwords since some of them are not used often.
So, where can I store them?
1) I do not want to store them digitally, since I am not sure if I do not have exploit which can just steal the file I am storing them. Actually VeraCrypt documentation told me that an encrypted volume/container is encrypted in disk all the time and it is decrypted into memory each time. But what is the problem to do exploit which is dumping memory some time or triggered by some website opened? I could do that.
2) I do not want to use a password manager since I do not trust them. Ok, I can find one open source project and do my own investigation. But the problem I am scared of is that if one password would be compromised, for example by keylogger + exploit stealing the password manager file and I am out of the business.
3) The best way to store them is physically on paper since I trust my environment the most. But this is also not a good case theoretically. I do not have a safe.
So what do you recommend? What is the ideal model to store passwords? Where do you store them? I mean about a serious password, so b) group of my listing. The a) group are stored in encrypted files on an external disk and this is equally like I would store them in a password manager. I mean 1 password cracked = all passwords available. However, I am plugging this disk rarely so I guess even it is a bit safer than a password manager.
