Under the EU Temporary Protection Directive, Ukrainian refugees fleeing the war are granted immediate protection across the EU, including a temporary legal residence permit.
Being a legal resident in the EU gives you among other benefits a right to a bank account with all basic features, free of charge or for a reasonable fee.
A basic bank account gives you access to the most common services you need in your daily life. You can deposit money in the bank and send money to other people online. You will also get a payment card to withdraw cash and make payments.
