Hold my beer for a few billion years while I crack it.
This is the kind of password I use to protect my actual secrets. So if someone is able to crack it, I'd like to know. The bounty is for a 'realistic' use case.
Choose a lyric from a favorite song. Concatenate the first letter of each word in the lyric. Example:
“Rock the Casbah Sharif don't like it”
Becomes:
rtcsdli
Add capitalization or numbers/special characters according to your own pref. For example, maybe your decide to alternate lower and upper case and always end with a bang:
rTcSdLi!
Although you have to use the same capitalization rules for all passwords if you have any hope of remembering them.
The combinations are easily in the trillions, likely much much more. Read the algorithm.
An algorithm for password generation is not security by obscurity.
> Although you have to use the same capitalization rules for all passwords if you have any hope of remembering them.
So no additional combinations from that. Your algorithm is simple and common enough that it's possible that an attacker can figure it out from a single leaked password. With one leaked password they've compromised all of your passwords to anything they have the capability of trying a few million passwords on.
Or 24h, flight tickets, and a wrench.
