How to Secure Your Angel One Account: Passwords, MPIN and Safe Habits

Published 2026-10-16 · Aadarna Stock Broking Pvt. Ltd.

Your trading account holds access to your money and shares, so it deserves the same care as your bank account. Most account takeovers happen through shared OTPs, fake apps or careless device use, not through technical hacking. This guide covers simple habits that protect an Angel One account.

Security settings change with app updates, so check the current options in the Angel One app or the support section of angelone.in.

Strong login security

• Use a strong, unique password that you do not use anywhere else.
• Keep two-factor authentication on. Logins to trading accounts require a second factor such as an OTP, MPIN, biometric or authenticator app.
• Set an MPIN that is not your birth date or an obvious number.
• Use biometric login on your own phone if available.

Never share these

• Login password and MPIN.
• OTPs of any kind.
• CDSL TPIN.
• UPI PIN and bank passwords.

This applies to everyone: callers claiming to be from Angel One, CDSL, SEBI or a bank, friends offering help, and Authorised Persons, including Aadarna. A genuine intermediary never needs them.

Device safety

• Download the app only from official app stores and check the developer name.
• Keep your phone locked with a PIN or biometric.
• Do not install remote-access or screen-sharing apps at anyone's request.
• Avoid logging in on shared or public computers. If you must, log out and clear the browser afterwards.
• Log out of old devices and review active sessions if the app shows them.

Alerts are your early warning system

Make sure your own mobile number and email are registered. You then receive:

• Trade alerts directly from the exchanges.
• Debit alerts from CDSL whenever shares leave your demat account.
• Bank alerts for every transfer.
• Contract notes after each trading day you trade.

If you see a trade, debit or pledge you did not make, act immediately: change your password, contact Angel One support, and inform your bank if money is involved.

Common fraud attempts

• Calls or messages saying your KYC will be blocked unless you click a link.
• Fake trading apps that imitate real brokers.
• Investment groups asking you to install a different app or pay into a personal account.
• Callers offering to fix a problem if you share an OTP.

Report suspected fraud to Angel One and on the national cyber crime portal. Read our article on [fraud warning signs](/blog/investment-fraud-warning-signs).

Frequently asked questions

I shared an OTP by mistake. What should I do?

Change your password and MPIN immediately, contact Angel One support through the official app, check your recent trades and holdings, and inform your bank if any money was involved.

Can I use the same password as my email?

It is safer not to. A unique password means a leak elsewhere cannot be used to access your trading account.

Will Aadarna ever ask for my OTP?

Never. If anyone claiming to be from Aadarna asks for an OTP, password or TPIN, it is a fraud attempt.
