precautions while using internet banking

Never access the e banking using a link that has been provided to you in an e mail. The Bank will never provide you the e banking link in an e mail nor will it allow or request you to open an e banking account online. The PIN/TAN system where the PIN represents a password, used for the login and TANs representing one time passwords to authenticate transactions. TANs can be distributed in different ways, the most popular one is to send a list of TANs to the online banking user by postal letter. Another way of using TANs is to generate them by need using a security token. These token generated TANs depend on the time and a unique secret, stored in the security token (two factor authentication or 2FA).
