According to AMBCrypto, recently, Gemini security engineer Brandon Arvanaghi said that using the same password on several websites is the root cause of most security vulnerabilities. The only way to overcome password security vulnerabilities is to use a password manager. He warned viewers that the SIM exchange might allow potential hackers to access phone numbers and highlighted a $24 million lawsuit against ATT. He concluded that the most effective way to protect your account on cryptocurrencies or other platforms is to use a secure key. These keys (such as Yubikey) will only provide physical access to the various accounts of the user.
