Ensuring password and online transaction protection
We shield the security of our digital channels and your online transactions with the use of modern electronic protocols.
Transaction identification factors
Optima bank has adopted advanced communications protocols and identification mechanisms for your personal data.
For the greater security of your transactions, as of 7.9.2023, an additional third identification step has been added for capital transfers exceeding €1.000 (within Optima bank or to another bank in Greece or abroad), implementing the new legal framework (i.e. the amended one, based on Article 22 of L. 5019/2023, Article 74 of L. 4537/2018).
More specifically, to complete your transactions, you will receive an additional one-time password (OTP) in your certified email.
The identification factors in our digital channels are:
- username & password, verified through biometric characteristics (e.g. fingerprint)
- one-time password (OTP) received through Viber / SMS or push notification, through which you approve your transactions
- one-time password (OTP) received in your certified e-mail
Furthermore, particularly for fund transfers, a new function provided through our digital channels, is the activation/deactivation of fund transfers to banks abroad, an option you now have directly through Optima e-banking and the Optima mobile app.
Personal e-banking passwords
For your security, the system requires you to change your password every 6 months. However, you may change your password as often as you want.
In addition, in order to access your e-banking easier, you have the option to set up your own user ID.
With the aim to provide you with more security, a one-time password (OTP) is requested and sent to your mobile phone upon every connection to Optima's e-banking system from a new browser or IP address. If you wish, you can save the devices you frequently use for logging in, so that you do not have to fill in a one-time password every time. For each connection from a new browser or IP address, an e-mail is also sent to you, so that if the connection was not initiated by you, you can contact us and we can block the device and anyone who attempts to connect from it.
🔒 Recovery of login details for Optima e-banking & the Optima mobile app
Recovering your user ID and creating a new password is now even easier and faster, ensuring optimum security!
