Instead of using an S, use a $.

That’s a pretty obvious substitution, so expand $ into the words DollarSign.

In DollarSign, substitute 0 (zero) for the letter “o” and “@“ for the letter “a”.

D0ll@rSign

Wait, now you have another S in your password. Better change it to a $.

D0ll@r$ign.

Hm. Better get rid of that obvious S substitution.

D0ll@rDollarSignign

Substitute zeroes and @s again? Sure.

D0ll@rD0ll@rSignign

Oh let’s make I an exclamation mark!

D0ll@rD0ll@rS!gn!gn

Let’s reduce the redundant use of D0ll@r into multiple of 2.

D0ll@rx2S!gn!gn

Wait, let’s reduce the redundant use of !gn into multiple of 2.

Doll@rx2S!gnx2
