Because an Oracle wallet contains user credentials that can be used to authenticate the user to multiple databases, it is especially important to choose a strong wallet password. A malicious user who guesses the wallet password can access all the databases to which the wallet owner has access.
Passwords must contain at least eight characters that consist of alphabetic characters combined with numbers or special characters.
Note:
It is strongly recommended that you avoid choosing easily guessed passwords based on user names, phone numbers, or government identification numbers. This prevents a potential attacker from using personal information to deduce the users' passwords. It is also a prudent security practice for users to change their passwords periodically, such as once in each month or once in each quarter.
When you change passwords, you must regenerate auto-login wallets.
