How to use the Palm to create and to administer good passwords (i)
With all the services that we used nowadays in Internet, and being the use of the computers and the networks habitual in the work or the studies, the number of user names and passwords which we must remember grow exponentially. For this reason, we fall in bad habits that finish completely with the security of the system. Although he is troublesome:
- We must avoid passwords that have some meaning, like our date of birth, our telephone, the name of our relatives etc.
- In the same way, it is necessary to avoid passwords that are own words or names in any language, since there are sophisticated programs of attacks by dictionary that reunite all these terms they are and them verifying systematically.
- Something that are very extended, and end its utility completely, that to write our passwords in a paper, and much worse still, to leave it in an accessible place like next to the keyboard.
- We would not have either to send our passwords by email, instantaneous mail, chat, etc, since the information travels without encriptar by these channels, reason why much people dedicate themselves to intercept them to secure valuable information.
- We do not have to use the same password for everything.
- And dice more and more the habitual danger that supposes phishing, never we must respond nigún email where they ask for our passwords or data to us, and less than the bank.
A chosen bad password is easy to break
�? stos advice will make us avoid these bad practices:
- We will try that our passwords are of at least 8 characters or more.
- The password must have letters in capital letters, small letters and numbers. If it also admitted to the system would be recommendable to add it to him some nonalphanumeric character like a hook, an asterisk, etc. This is because programs of attacks by brute force exist that are proving all the possible combinations, so that the more it releases is our password and the more variety of elements contains, I number of combinations to try will grow extremely.
- We will try to change the password periodically.
- Finally, a good rule to invent a password can be the use of the first letters of verses, songs, proverbs, etc, whenever they contain all that variety of characters. This I found it example a long time ago, and it seemed to me very explicit:
“But it is worth bird in hand
That 100 flying”
From this proverb I have indicated in bold the characters that we could use for our password, thus being: “MvpemQ100v”.
We have secured a password of 10 characters that contains all the basic ingredients that we commented: letters in small letters, capital letters and numbers. The result would be “MvpemQ100v”
Now that we know how they must be and how to preserve our passwords, comes the moment for taking it to the practice. But, how we can take in the head so many if above they have to be long and complicated? In next post we will see that our Palm will make this task a game of children, at the same time as it adds more security to the system.

Brilliant post. Finally encounter a useful system to remember safe passwords! A greeting!
The cuesión and always to know how to organize themselves, and to have these small tricks
It had listened to previously some advice on passwords but not the one of the proverb, interesting.
Personally, my profiles of user and passwords I keep in my TE2 like a file *.pdb (encriptado) that I abro with MobileDB of handmark (very good application besides gratuitous) this way to accede to bnco of passwords is necessary to know two keys, which are the only ones that memory since others are generated.
Saludetes, good annotation!
