uTrade AlgosA common concern with phone number-based login systems is whether simply knowing your phone number could allow unauthorised access to your account. Fortunately, the security design of these systems ensures that having your phone number alone is not enough.
Verification Codes and Security
When you log in using your phone number, the system sends a one-time password (OTP) or verification code to your device. Without this code, an unauthorised person cannot access your account, even if they know your phone number. This extra step is a critical security measure that Share India‘s recent support feature of phone number-based login utilises to protect users.
Physical Security of Your Device
While knowing your phone number doesn’t grant access, the physical security of your device is crucial. If someone has your phone, they might receive the verification code needed to log in. Therefore, securing your device with a strong passcode or biometric authentication adds an essential layer of protection.
Two-Factor Authentication
For added security, many platforms, including those supported by Share India, offer two-factor authentication (2FA). This requires an additional verification step beyond the phone number, further safeguarding your account against unauthorised access.
In conclusion, simply having your phone number does not allow someone to access your account. However, maintaining the security of your device and enabling extra authentication measures are important steps to keep your account secure.
