Is it unsafe to reuse the same username and password for multiple accounts?

[vampire9545]

mathmatically i would say it is unles safe than using multiple ones. however, what safer easy knowing ur login info or not remembering if u used this email for this site or that one for this one. I use same screen name but different @addresses for some. and i cycle through 3 passwords, based on how serious i take the site n how serious the site is, also if the site requires the new needs a number,capital letter and !@# ect stuff.

keep in mind, that passWORDS,like pokemon, r more likely to be compromised than say p0k3m0n or n0m3k0p.

the math says,if the system is letters and numbers, the odds r 62^x, x being amount of characters. so a 6 character alphanumeric password would be 1/56,800,235,584, chance of guessing it.
