In recent days, Piraeus Bank has been sending emails reporting account locking, and urging (requiring) users to unlock their accounts by changing their password. 
The email states:
In recent days, Piraeus Bank has been sending emails reporting account locking, and urging (requiring) users to unlock their accounts by changing their password. 
The email states:
Non-execution of postdated/repeated orders due to deactivation of Piraeus e-banking codes
Due to the deactivation of your Piraeus e-banking passwords, we would like to inform you that in case you have entered postdated/repeated orders through the Piraeus e-banking and Piraeus app channels, their execution will not be able to be completed, for the period of time that your passwords remain inactive.
To reactivate your access to Piraeus e-banking, call +30 210 3288000.
So after contacting us on this phone, they gave us instructions on how to change the password and username. Because we asked friends, in other cases only the password was changed.
Therefore, because changing passwords requested by companies via email is not a good sign, and is usually done after a serious security incident, Piraeus should provide explanations.
What happened suddenly and massively changed passwords, and why did he use this method to change passwords, since he could have done it without sending an email.
It should be mentioned that in any case, the bank's policy requires changing the password at least every six months...
Shouldn't the customer know? So that no paranoia is created...

Although the press releases will range from very select to rare, I said I'd pass...because sometimes the editors hide.
The problem lately mainly concerns the use of VPN. The Piraeus system has become more sensitive when connecting from a foreign server and immediately locks the account. However, with a phone call they unlock it immediately
This report has nothing to do with it. This email is clearly automated and is sent as an informational message if the customer locks their internet banking passwords due to 3 incorrect login attempts. Essentially, it informs you that because the passwords are locked, if you have set recurring/postdated orders (transfers to third parties, remittances, etc.), as long as the passwords remain locked, these orders will not be executed. It's that simple.
If you read the first line of the email carefully, it says "Non-execution of postdated/repeated orders due to deactivation of Piraeus e-banking codes".
The same thing happened about two months ago with a national bank cashcard, where they had blocked them without informing the customer user due to numbers and passwords being leaked online...
Very true. I completely agree.
