No. Not without a proper examination by someone who knows historical cryptography techniques, those used before computers. I'd expect the only real threat to be an automated transformer AI solution actively looking for these types of algorithmic passwords, and one which already has access to a few of my passwords. Which is extremely unlikely given that no one uses algorithmic passwords. I was using a separate algorithm for more critical things, like my Google account but I deemed it unnecessary after some time because there is virtually no chance someone will crack it.
Though I should admit I still didn't migrate all my passwords to the latest and safest specification of the algorithm.
Only using digits limits the probabilities space drastically.
- pil0u 3y agoI won't come at you, for lack of time and expertise. I'm genuinely interested in that approach, but I'm probably too afraid to design an algorithm that would be vulnerable for reasons I couldn't imagine. For digit-only, I meant platforms that forces you that requirement - my bank does. What about MFA?
- Aerbil313 3y agoCurrently I use custom passwords which I write down in a single file for digit-only passwords. But while I was writing my top comment, an idea about converting letters in app/website name to digits and scrambling them came to me. Take a look for the algorithms: https://www.google.com/search?q=historical+cryptography+techniques https://www.google.com/search?q=historical+cryptography+tech... Choose one which you can run in your head, don't use it as-is, insert random chars at certain places, substitute some letters in the app name for others, make sure it looks like randomly generated, and you will be fine. I still use 2FA with Authenticator (on iPhone), fallback set as SMS. Only thing I need is my government issued ID to get a new SIM card if the current one burns.
