Many sites or apps ask you to sign up to the site to access the personalized content. Few of them ask you to change the password at regular intervals to ensure the security of the account. Every time you have to change the password after the period, your question would what should my next password.
This is most common and happens with every one, as they will runout of passwords (mainly after using nick names, pet names, simple texts and so on). This article helps you to choose next the password.
Most common mistake people make in choosing the passwords is, choosing a most common password, like "password" ,"abcd123", "qwerty", "123456".... This makes an attacker to login to your account and steal the data or do some actions with the account.
Since the goal here is to ensure the security of the account, no one else should be able to guess your password, so it should be unique. And a password will be unique when it is created by you by imposing personal thoughts. One such strategy is, if your password is expiring every 3 months, think of your goal for next 3 months, and set that as the password.
For example, if you have a goal to buy a car, you could set as Honda0821$. Or if your goal is to visit a place , you can set it as Texas3Q21$.
This strategy also helps in reminding your goal every time you key in the password.
In few rare cases, you will have to share the password, but you may not want to disclose the goal. For those users, set the password as "Ufybt3Q21$" instead of "Texas3Q21$". Here every letter of "Texas" is replaced with the next character in the alphabets order. This way, though you had to share the password, your goal is not disclosed to them.
