Ends with a quick 4-question self-audit and a promotional mention of Coinlyx exchange. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Should I use an authenticator app or SMS for two-factor authentication on my crypto exchange account? An authenticator app is safer than SMS-based two-factor authentication for crypto accounts. SIM-swap attacks let criminals intercept SMS codes, making text-message-based 2FA weaker than app-based codes. Enabling 2FA on every account that supports it adds a second lock even if a password is compromised, and an authenticator app closes the SIM-swap gap that SMS leaves open. _daily.dev surfaces practical security habits for anyone hardening accounts against SIM-swap and phishing attacks._ ### What is the safest way to store a crypto wallet seed phrase? The safest approach is writing the seed phrase on paper or stamping it into metal for fire and water resistance, then storing it offline in two separate physical locations as a backup. Never photograph it, store it in cloud notes or email, or type it into any website or app, since cloud accounts get breached and phishing sites exist specifically to harvest seed phrases. _Readers weighing cold storage options can track security best practices for crypto custody on daily.dev._ ## Similar posts on daily.dev -
