How to Create Strong Passwords and Use a Password Manager
A strong password routine has two goals: make each login hard to guess and prevent a problem with one account from spreading to others. A password manager makes that routine easier by generating and storing different passwords for you. You can start with a few important accounts instead of changing everything in one sitting.
Give every account its own password
Reusing a password connects accounts that would otherwise be separate. If one service exposes it, criminals can try the same login elsewhere. Small changes, such as adding a site name or changing the final number, do not create a reliably independent password.
Start with your main email account, then your password manager, financial accounts and accounts containing private documents. Email deserves early attention because other services often send password-reset messages there. Keep a checklist of account names and completion dates; do not put the passwords in that checklist.
Create passwords you do not have to invent
Use your manager’s generator for long, random passwords that meet each service’s requirements. Let the software remember the result. Avoid personal details such as birthdays, pet names and favourite teams, which other people may know or find online.
For a password you must remember, choose unrelated words rather than a quotation or predictable sentence. The UK’s National Cyber Security Centre describes three random words as one practical approach. Follow your manager’s own guidance for its master password, and never copy a sample password from an article.
Choose a manager that fits your devices
Before moving your logins, check these practical points:
- Does it work on the phones, computers and browsers you actually use?
- Can you protect the vault with multifactor authentication?
- What happens if you forget the master password or lose a device?
- Can you export your data if you later change providers?
- Can you clearly understand its backup and recovery instructions?
Download the application or extension through the provider’s official website or your device’s official store. Read the recovery instructions during setup, while you can still access everything. A recovery method is only useful if you can find and use it when something goes wrong.
Move accounts in small, verified steps
- Open an account through a saved bookmark or an address you know.
- Use its password-change screen to set a generated password.
- Save the new login in your manager and check the website address attached to it.
- Test the new login before removing your old record.
- Mark that account as complete and move to the next one.
Try one low-risk account first if you are unfamiliar with the manager. This gives you a chance to learn the save and autofill process before changing your primary email login. Work slowly enough to confirm which username belongs to each account.
Protect the vault and respond to warning signs
Use a unique master password, enable the manager’s available extra sign-in protection and lock your device when you leave it. Keep recovery materials somewhere secure that you can reach without relying entirely on the same device.
If a service reports an exposed password, change it through the genuine service and replace any reused copies elsewhere. Review unfamiliar account activity too. Passwords are one part of account security; updates, careful sign-in habits and multifactor authentication still matter.
