I think seed phrases are the best since you can always recover the wallet on any software if something happens to alby. Also as a side note, where is the option to delete my alby account? I made one to test a few things and I donโt want it anymore. Also double side note, I think you should add an option to drain the wallet to an on-chain address because when trying to empty the wallet itโs impossible to get to 0 sats due to needing some reserve for lighting fees
