ANDROID and iPhone users should think twice if they receive a seemingly innocuous text, as it could signal a cyber attack.
Some sites use one-time password codes, which provide an additional layer of authentication before users log into their accounts.
Google, for example, may send a security code via text message to confirm your identity. You can only use it once and it will expire after a few minutes.
However, if you didn’t request a code, it could mean that a bad actor is trying to gain access to your accounts.
An unsolicited OTP code may indicate that your account has been compromised.
A hacker could know your username and password or just some credentials, causing the website to detect suspicious activity on your account.

If you receive a surprise OTP code, quickly change the password for that account.
The code could also be part of a larger effort, such as a phishing scam, in which cybercriminals trick their targets into clicking on a link or attachment.
This link could lead to a spoofed website that asks for your login credentials, revealing them to the hacker.
However, an OTP code can be a sign of an honest mistake.
Another user may believe they are logging into their own account if they have a similar username with just a few letters or numbers separated.
This is more likely for platforms that only ask for a username and OTP code to log in.
However, prevention is better than cure – and there are easy ways to stop your information from falling into the wrong hands.
Consider using a password manager that can generate and store strong passwords.
While 12 characters were once considered sufficient, experts now say a secure password should be 16 or more and use a healthy combination of numbers, letters and special characters.

You can also set up an additional form of authentication on accounts that allow this.
The most secure option is biometric technology, which relies on unique identifiers such as a fingerprint or facial scan.
Since the OTP code is intended to provide another layer of security, avoid sharing it with anyone.
If someone calls or texts you asking for an OTP code, do not provide it as it will give you unobstructed access to your account.
How to keep your iPhone safe
Although Apple’s iPhone operating system has a reputation for being secure, you can always take steps to be even more secure. Here’s what Mackenzie Tatananni, science and technology reporter for The US Sun, had to say.
One of the easiest ways to avoid being hacked is to download the latest software updates, which often contain patches to fix vulnerabilities.
You can also keep your iPhone up to date with the latest software by turning on automatic updates.
When looking for software, apps, or anything to download to your iPhone, only look for trusted sources.
The official App Store is just one example – all apps in it have been vetted by Apple, not third-party sources.
You should also be careful when downloading text or email attachments.
Do not click on suspicious attachments or links if you have not confirmed their origin.
They may inject malware into your phone or capture your personal information under the guise of it being from a trusted source, such as a bank or employer.
To take steps to protect your data from interception, avoid connecting to public WiFi networks.
If necessary, be sure to use a virtual private network or VPN – there are tons of options in the App Store.
It’s also important to stay vigilant and monitor your accounts for other signs of violations.
If you received an OTP code for your bank account, for example, be on the lookout for unusual activity.
This could include unknown transactions or purchases, large money transfers, or changes to your credit score.
