class=\"wp-block-heading\" id=\"how-to-use-a-generated-password\">How to use a generated password<\/h2>\n<p class=\"wp-block-paragraph\">A random password is only useful if you never have to remember it. Generate one, paste it straight into a password manager as you create or update the account, and let the manager fill it in from then on. Do not email it to yourself, save it in a note, or reuse it on a second site. If you need to check an existing password instead, use our <a href=\"https:\/\/securitybriefing.net\/vi\/cong-cu-kiem-tra-do-manh-mat-khau-mien-phi\/\">password strength checker<\/a>.<\/p>\n\n<h2 class=\"wp-block-heading\" id=\"how-long-and-complex-should-it-be\">How long and complex should it be?<\/h2>\n<ul class=\"wp-block-list\">\n<li><strong>16 characters or more.<\/strong> Length is the single biggest factor in how hard a password is to crack.<\/li>\n<li><strong>Mix character types when the site allows it,<\/strong> but do not sacrifice length to fit a short symbol-heavy pattern.<\/li>\n<li><strong>One password, one account.<\/strong> Generate a fresh password for every login so a single breach cannot cascade.<\/li>\n<\/ul>\n<p class=\"wp-block-paragraph\">Gaming accounts are a common target for credential-stuffing attacks, since players often reuse the same password across multiple platforms. If you play online, see our guide on <a href=\"https:\/\/securitybriefing.net\/cybersecurity\/how-safe-is-gaming-online\/\">how safe is gaming online<\/a> for the risks specific to gamers.<\/p>\n<p class=\"wp-block-paragraph\">Passwords generated here are created in your browser. Explore the rest of our <a href=\"https:\/\/securitybriefing.net\/vi\/tools\/\">free security tools<\/a> for hashing and email header checks.<\/p>\n\n<h2 class=\"wp-block-heading\" id=\"faq\">C\u00e2u h\u1ecfi th\u01b0\u1eddng g\u1eb7p<\/h2>\n<h3 class=\"wp-block-heading\" id=\"are-generated-passwords-stored-anywhere\">Are generated passwords stored anywhere?<\/h3>\n<p class=\"wp-block-paragraph\">No. They are generated in your browser. Copy the one you want into your password manager, and it is gone from this page as soon as you leave.<\/p>\n<h3 class=\"wp-block-heading\" id=\"do-i-need-a-password-manager-to-use-these\">Do I need a password manager to use these?<\/h3>\n<p class=\"wp-block-paragraph\">It is strongly recommended. Long random passwords are only practical if something remembers them for you, and a manager also stops you reusing the same password across sites.<\/p>","protected":false},"excerpt":{"rendered":"<p>M\u1eadt kh\u1ea9u c\u1ee7a b\u1ea1n c\u00f3 an to\u00e0n kh\u00f4ng?
