I think brave should create a new feature with an account with login credentials to save our wallet id info and for linking or delinking wallet id to uphold.
Uninstall and reinstall brave browser will wipe out our wallet id info and it will be bad if it is linked to uphold.
We may never get to delink them from uphold if we forgot the wallet id because of the current max 4 limits to link to uphold.
There should be at least a manual method or solution to backup current brave wallet to somewhere and restore back to the browser instead of creating new brave wallet id after fresh installation.
