a very neat Pro feature is @CoSoGuard
it lets you know if your registered email address has been the subject of data breaches elsewhere on the internet.

Be a Bro and Go Pro. There's lots of really good perks here in CoSo.

also, please, for all that is Holy, #EncryptYourShit, use complicated passwords or passphrases.

....and clear your internet history every now and then, you'll be glad you did lol
