How to Create a Strong Password You Can Actually Use
A strong password is long (12–16+ characters), unique for each account and hard to guess – a random string from a password generator or a passphrase of four or more unrelated words. Store passwords in a password manager and turn on two-factor authentication for important accounts.

Create and test a password – step by step
Step 1: Generate
🔐 Use the Password Generator to create a long random password.
Step 2: Or build a passphrase
Pick four or more unrelated words, add separators and a number.
Step 3: Test it
Check it with the Password Strength Checker – do not test your real banking password on any website.
Step 4: Store it safely
Save it in a password manager, not in a notes app or on paper near your computer.
Habits to drop
✓- Reusing one password everywhere – one breach unlocks every account.
- Using names, birthdays, phone numbers or your city.
- Sharing passwords over WhatsApp or email.
- Saving passwords in plain text files.
Protect PDFs too
The same rules apply to document passwords: use a long passphrase when you protect files with Lock PDF, and send the password separately from the file.

Perguntas Frequentes
How long should a password be?
At least 12 characters, and 16 or more for important accounts like email and banking. Length matters more than complexity.
Are passphrases safe?
Yes. Four or more random, unrelated words – for example "Lantern-Mango-River-Quiet-82" – are long, strong and memorable.
Is it safe to generate a password online?
Use a generator you trust and a private device. Better still, let a password manager create and store passwords for you.
Should I change passwords regularly?
Current guidance says change a password when there is a reason – a breach or suspected misuse – rather than on a fixed schedule. Use a unique password for every site.
What is two-factor authentication?
A second step at login, such as a code from an app. It protects your account even if the password leaks – turn it on wherever possible.
How do I know if my password leaked?
Check your email address on a breach-alert service such as Have I Been Pwned, and change any password that appears.
