You can use the following strategy to find a secure and variable password: Find a practically ‘uncrackable’ base/master password and then add a certain extension to it for every different web portal that you visit. A possibility would be to combine the master password with the name of the service, for example, PayPal or Ebay.
Example of a password strategy
When using the strategy mentioned above you certainly would not choose “master password+Ebay” as your password. You would instead omit the vowels or the second or third letter of the supplier and replace them in certain places in the master password, for example, always second, third and last position.
Say that your master password is G5w.&$;(9b.B and you want to create a password to use on Ebay. You could use the first and last letter of the company, which in Ebay’s case would be e and a, and place them at the end and third to last spot of the master password. Using a number to denote the length of the company’s name is also a convenient tactic. So for Ebay the password would be
4G5w.&$;(9bE.Ba and a further example would be PayPal: 6G5w.&$;(9bP.By.
Only use a master password for trustworthy websites
Even with sophisticated systems there is still a danger. If someone works out the pattern they could then use it to hack another account; therefore it is advisable to only use the master password on sites that are 100% trustworthy. You should use a different password for sites that are less important and less secure. Forums and communities, which are known to be less secure, offer the option of disposable passwords that can be used just once.
