Thats one way, I suppose, but the calculator seems to work with spaces and other special characters.
I’m not in the habit of sharing passwords to accounts I own with anyone, so outside of my password manager, only I would know it.
And the ammendment itself could be anything relevant to the account. I just used ‘Lemmy Instance’ as an example. Could be the domain, the site title, the number of people I follow, the developer, a random word or nickname I think of (i.e. twitter= bird app). Literally anything.
The ammendment, by itself, is what goes into the password field of my manager.
That way, I don’t need to know the actual password of the account, I just need to remember the master password and use my password manager to retrieve the ammendment.
The combination of these two things should result in a never changing hash.
This is just a method I am testing out (for now) since I am working with limited access to the accounts I own.
