Sharing Sensitive Data Safely: Why Chat Apps Might Not Be Enough

We send data through LINE, Messenger, or Email every day. But did you know that this information can be intercepted or stored in the cloud longer than you think? For passwords, credit card info, or company secrets, standard messaging might be too risky.

1. Encrypt Before You Send

The most secure way is to make the data unreadable to anyone without a key. Using AES (Advanced Encryption Standard), a global security standard, ensures your secrets stay secret.

• Try it now: AES Data Encryption Tool — Encrypt your message and send only the "code" to your recipient. Share the password via a separate channel.

2. Check Your Password Strength

Weak passwords like "123456" or "password" are the biggest vulnerabilities. A strong password should be long and include a mix of characters.

• Test your password: Password Strength Checker

3. Mask PII Before Sharing Screenshots

Before sending screenshots or documents, ensure that Personally Identifiable Information (PII) like names, phone numbers, or ID numbers are censored to prevent identity theft.

• Censor your data: PII Masker

Security Best Practices

• Never reuse passwords: Use a password manager or random generators for each site.
• Verify the recipient: Always double-check who you are sending sensitive files to.
• Delete after use: Once the recipient confirms they have the info, delete the message from the chat history on both ends.

Security starts with you. Using these small steps and tools can significantly reduce your risk!
