Use a long unique passphrase for every account
Ψηφιακό ΑπόρρητοGive each account its own long, random, unique password and let a password manager remember them.
- One reused password
- Unique per account
- Manager remembers
Βήματα
- Make each password long (aim for 16+ characters) and unique to that one account.
- Prefer a passphrase of 4-7 unrelated words, which is long yet easier to recall.
- Install a reputable password manager to generate and store a different password per account.
- Protect the manager itself with one long master passphrase you keep only in your head.
- Stop reusing or lightly tweaking one password across sites.
Γιατί λειτουργεί
Long, unique passwords mean a breach of one site cannot unlock the rest, and a manager makes that practical without memorizing dozens.
Χρήσιμο να γνωρίζετε: Modern guidance (NIST/CISA) drops forced periodic resets; only change a password when it is weak, reused, or exposed in a breach.
Πηγή: CISA (Secure Our World)Turn on multi-factor authentication
Ψηφιακό ΑπόρρητοAdd a second login factor so a stolen password alone cannot open your account.
- Password
- Plus app code
- Account opens
Βήματα
- Open the security settings of each important account (email, bank, social) and enable MFA / 2FA.
- Choose an authenticator app or a hardware security key rather than text-message codes when offered.
- Save the backup or recovery codes the service gives you somewhere safe.
- Repeat for every account that offers it, starting with email since it can reset others.
Γιατί λειτουργεί
MFA requires a second proof beyond your password, so an attacker who steals or guesses the password still cannot get in.
Χρήσιμο να γνωρίζετε: CISA warns SMS codes can be intercepted (SIM-swap); use an authenticator app or FIDO security key where possible. App codes still beat nothing if that is all a site supports.
Πηγή: CISA (Secure Our World)Freeze your credit at all three bureaus
Ψηφιακό ΑπόρρητοA free credit freeze stops thieves from opening new accounts in your name.
- Thief opens credit
- Freeze blocks it
Βήματα
- Contact all three credit bureaus: Equifax, Experian, and TransUnion.
- Request a free credit freeze with each one (online or by phone is fastest).
- Save the PIN or login each bureau gives you so you can lift the freeze later.
- Temporarily lift the freeze only at the bureau a lender will check, then refreeze when done.
Γιατί λειτουργεί
Lenders usually will not extend credit without seeing your report, so a freeze blocks identity thieves from opening new accounts in your name.
Χρήσιμο να γνωρίζετε: A freeze must be placed at all three bureaus to be effective; placing it at only one leaves the others open. It does not affect your credit score and is free to place and lift.
Πηγή: Federal Trade CommissionSpot phishing and never click unexpected links
Ψηφιακό ΑπόρρητοTreat urgent, unexpected messages asking you to click or confirm info as likely scams.
- Urgent message
- Do not click
- Verify yourself
Βήματα
- Be suspicious of unexpected emails or texts claiming an account problem, suspicious activity, or a refund.
- Do not click links or open attachments in messages you did not expect.
- Ask: do I actually have an account with this sender? If not, it is likely phishing.
- Verify by contacting the company through a phone number or website you look up yourself, not the message.
- Report it: forward phishing texts to 7726 (SPAM) and report to ReportFraud.ftc.gov.
Γιατί λειτουργεί
Phishing messages impersonate trusted companies to trick you into handing over passwords or account numbers; not clicking and verifying independently defeats them.
Χρήσιμο να γνωρίζετε: Legitimate companies do not email or text a link asking you to update payment details; a familiar logo or name does not prove a message is real.
Πηγή: Federal Trade CommissionKeep your software and devices updated
Ψηφιακό ΑπόρρητοInstall updates promptly and turn on automatic updates to close known security holes.
- Unpatched flaw
- Update closes it
Βήματα
- Install software and operating-system updates as soon as you are notified, especially critical ones.
- Turn on automatic updates in your device and app security settings.
- Prioritize updates for your web browser and security/antivirus software.
- Apply updates to your phone, computer, and other connected devices alike.
Πηγή: CISA (Secure Our World)Γιατί λειτουργεί
Many updates patch security flaws that criminals exploit to reach your files or accounts; installing them quickly is what actually delivers the protection.
Review and minimize app permissions
Ψηφιακό ΑπόρρητοCheck what your apps can access and switch off permissions they do not need.
- Open privacy settings
- See app access
- Switch off extras
Βήματα
- Open the privacy settings on your smartphone to see what each app can access (location, contacts, photos).
- Turn off permissions an app does not need to function.
- Delete apps that demand lots of permissions unrelated to what they do.
- Review the privacy settings on connected TVs and streaming devices too.
Πηγή: Federal Trade CommissionΓιατί λειτουργεί
Apps often request more access than they need; trimming permissions limits how much of your personal data they can collect and share.
Lock devices with a strong passcode plus biometrics
Ψηφιακό ΑπόρρητοSet a strong PIN or password as the root unlock and add fingerprint or face for convenience.
- Long passcode
- Add biometrics
- Backups encrypted
Βήματα
- Set a screen lock on every device using a PIN, pattern, or password.
- Choose a longer code over a short one: a six-digit-or-longer PIN beats four digits.
- Add fingerprint or face unlock as a fast layer on top of, not instead of, the passcode.
- Use that screen lock so automatic and manual backups are encrypted.
Γιατί λειτουργεί
A strong device lock keeps anyone who finds or steals your phone from reaching your accounts, messages, and stored data, and it encrypts your backups.
Χρήσιμο να γνωρίζετε: Biometrics are a convenience layer; the PIN or password remains the true root of trust, so keep it long and never set it to something guessable like 1234.
Πηγή: CISABack up your important data
Ψηφιακό ΑπόρρητοKeep a copy of your files on an external drive or in the cloud so an attack cannot wipe you out.
- Copy your files
- Drive or cloud
- Restore anytime
Βήματα
- Back up the data on your computer to an external hard drive or to the cloud.
- Back up the data on your phone too.
- Turn on automatic backups so copies stay current without you remembering.
- Confirm the backup is protected by your device screen lock so it is encrypted.
Πηγή: Federal Trade CommissionΓιατί λειτουργεί
A current backup means ransomware, theft, loss, or a failed device cannot permanently destroy your photos, documents, and records.
Stay safe on public Wi-Fi
Ψηφιακό ΑπόρρητοMost sites are encrypted now, so check for HTTPS and keep accounts protected on public networks.
- Public Wi-Fi
- Check for https
- MFA + logout
Βήματα
- Confirm a site is encrypted: look for a lock symbol or https in the address bar before entering anything.
- Only log in or enter personal info on sites that use encryption, and log out when you finish.
- Use strong unique passwords and turn on two-factor authentication for your accounts.
- Keep your operating system, browser, and security software updated, with automatic updates on.
Γιατί λειτουργεί
Widespread HTTPS encryption makes public Wi-Fi usually safe, so verifying the connection and locking down your accounts covers the real remaining risk.
Χρήσιμο να γνωρίζετε: Encryption only protects data in transit; a scammer's own fake site can still steal what you type, so do not email financial details and watch for impersonator sites.
Πηγή: Federal Trade CommissionCheck breaches and change exposed passwords
Ψηφιακό ΑπόρρητοSee where your email has leaked, then change those passwords and add 2FA.
- Check your email
- Reset exposed
- Add 2FA
Βήματα
- Check whether your email has appeared in known breaches using a reputable tool like Have I Been Pwned.
- For every breached site, change that password to a new long unique one (a password manager helps).
- If you reused that password anywhere else, change it on those accounts too.
- Turn on two-factor authentication on the affected accounts.
- Delete old accounts you no longer use to shrink your exposure.
Γιατί λειτουργεί
Reused passwords let one breach cascade into your other accounts (credential stuffing); changing exposed passwords and enabling 2FA stops the chain.
Χρήσιμο να γνωρίζετε: Watch for follow-on phishing and strange medical or financial bills after a breach, and consider freezing your credit if sensitive identity data was exposed.
