A wallet session permission may let an application perform defined operations without the usual confirmation each time. Before accepting, identify the account, actions, assets, duration and stopping mechanism. The word session does not establish that authority ends when the page closes.
Possessing an encrypted wallet file does not make it importable into any program. You need its format, the password that protected it, a compatible import path and knowledge of which accounts it covers. A failed import does not establish that the balance disappeared; preserve the original while diagnosing the failure.
Disabling withdrawals restricts an important API function, but does not make a key financially or privately harmless. It may still read account data, place orders or cancel them. Begin with the application's tasks, then grant the supported access those tasks actually need.
Saving a withdrawal address does not necessarily prevent sending anywhere else. The feature might be a convenience address book or an enforced list with rules for changes. Check what the service blocks, who can modify it, when changes take effect and which access routes it covers.
SMS codes, authenticator-app codes and passkeys are not identical against phishing. Compare how each verifies access to the intended service, what happens after device loss and which alternatives the account still accepts. Review normal use and recovery together before changing methods.
