There is no "database link" in KeePass. There is your database, a single file usually ending in KDBX, and a KeePass app to open the database. Open a file manager on your phone and search for the database file. Open the KeePass app and then use it to open the database. cheers, Paul p.s. and make a backup of the database file when you find it.

Exactly what error message do you get when the database won't open? Can you post a screenshot? (Save the shot as PNG and click the "Add attachments" button just above the "Post" button.) cheers, Paul

It's not a hidden bug, it's you mis-typing the password on the W10 machine. Make a new test database with a simple password. Test it on all machines, from GD and USB. cheers, Paul

I assume you meant the Expired Entry pop-up is suppressed? This seems like the correct behaviour, otherwise you get more than one pop-up and some confusion. I would just click on Find > Expired for each database. cheers, Paul

It's always the password that is wrong! Type it in Notepad and then paste it into KeePass. Are you sure you are trying to open the file you created on the W11 machine? Did you copy it to a USB and then open it on the W10 machine? If not, try it that way. cheers, Paul

Exporting XML is a much better method because it contains all fields and history. The password does not get corrupted. The only time the encryption is changed is when you save the database after changing the password. If you did not save the database there is no possibility the password required to open it will be different. You can test this by restoring an old version from GD and opening it. If it doesn't open you are using the wrong password. cheers, Paul p.s. I suggest you make independent backups...

Use KeePassHttp, KeePassRPC or KeePassNatMsg will give you an interface to KeePass. https://keepass.info/plugins.html cheers, Paul

You may have set KeePass to go to the Tray. This places the icon in the bottom right corner. Sometimes you need to click the Up arrow. cheers, Paul
