Can I use my wallet on a browser of a friend or on a public device?
You can access to the wallet from any device using the backup (the credentials). These should be used only on the first access from that device because it will be saved on it. The next time just use your PIN to access. You must be careful if you want to access from a public device because your credentials are saved on it, so at the end of you must delete the credentials from the wallet settings, dangerous area, delete the credentials.
