A few years ago, passwords were topic just for network administrators. Today we need a password for everything, and in addition PIN for credit cards and cell phones. All passport parameters are strictly determined with specific safety requirements. Therefore, it is quite understandable that recent analyses show that many people choose simple combinations such as "abc123", or have one password for everything. However, with regard to safety this is not recommended.
The basic problem with passwords is that the secure ones are hard to remember and easy-to-remember passwords are not safe. Some viruses spread even by guessing the most likely passwords. They easily penetrate into one system our of every 100.
Another security option is using touch sensors. However, there are special hardware requirements to use them. In contrast, a combination of keys is the cheapest security option.
Making up a secure, easy-to-remember password
There are several recommendations. For example, illogical combinations of words such as "dog torch stapler." Phrases are safer than one-word-passwords, but most people opt for combinations that have a semantic relationship. Such are predictable, and therefore, insecure.
Another option is to change a sentence or a phrase in a password. Use the first letter of each word in a sentence, and if possible, replace some words with symbols and numbers. For example, "Jules Verne wrote Two Years' Vacation and A Captain at Fifteen" will transform in "JVw2YV&ACa15". However, avoid choosing a name of a song or a proverb.
