( Not sure this is the appropriate section to post it ) I read sometimes that secure password can be long nonsense phrases, that would have the vantage to be long and easy to memorize. For example one password could be: " red furnitures ride deserts that eat some stupid onion ": is it true ? is it tested ?
No problem ! English is not my native language. But why ? A long phrase is anyway a combination of letter: softwares that try to find the combination make not difference between languages, they try combinations.
If they are going to use brute-force then language doesn't matter. If dictionary attack is conducted, passphrases in some languages can be a little "safer" than in other.
In retrospect: if I use a nonsense phrase very long no matter which language I use: anyway the phrase has not sense, so no automatic dictionary can guess it, because it is only a sequence of letter. Different the case if I used " To be or not to be...": here a structured literary dictionary could be find it easy.
If seen some password apps that have a pretty neat way of dealing with the password problem you think of a master password. Then in the app, for each site you put in a name for the site, then your username which it saves. To get the password to use for the site you just enter the master password. The app then combines your name for the site, your username and your master password and applies a hash algorithm to it. So the resulting password is a hash of all that. The upshod is. The passwords are not saved on the device they are generated only when you enter the master password. Every site ends up with a different secure password. Using a new master password changes all the passwords at once. I have seen several of these apps around using various different hash algorithms to do it.
That reminds me of this article and calculator about password haystacks: https://www.grc.com/haystack.htm
Yes that looks like one of them that idea is probably close to an ideal solution for the so many sites, so many passwords problem
Ya but, I'm thinking, an automatic dictionary with an autocomplete function, like Google uses for example, could complete and recognize the words of the phrases: " red furnitures ride deserts that eat some stupid onion " = the program finds R, then it finds E, so it completes = RED, and going on..... - I have not concerns or problems about my passwords ! Neither I have special security requirements except privacy: it's only a theoretical question.
