Can I switch an SFTP account from a password to a private key?
Short answer: Yes. Click Edit, switch Sign in with to Private key, choose the key file (and passphrase if needed), save and test. Install the public key on the server first. The nickname and transfers stay the same.
Yes. Select the account, click Edit, change Sign in with to Private key, choose the key file with Browse… (and enter its passphrase if it has one), then save and click Test connection.
Add the matching public key to the server first, or the test will fail. The account keeps its nickname, so transfers that use it carry on unchanged.
