Yes, you can change the Account register name used in Quicken. For each account, go into Edit Account Details and, in the General tab, change the Account Name to the name you want to use, e.g., “Chase UA 1234” (where 1234 is the last 4 digit of the card number)
Hello @JM-GCO,
Thank you for reaching out to the Quicken Community with this question.
Unfortunately, you are unable to edit the name of the Financial Institution as that comes directly from their servers and is the name of the particular instance that you connected to when adding your accounts.
I hope this clears things up!
You are very welcome.
Please do not hesitate to reach out with any further questions or concerns.
