Confirm the step first, then use the newest code.<\/p>\n<p><strong>Q2: How many times should I resend an OTP?<\/strong><\/p>\n<p>A: Keep it minimal. One resend after waiting a couple of minutes is usually smarter than repeated rapid retries, which can trigger throttling or confusion with multiple codes.<\/p>\n<p><strong>Q3: What&#8217;s the difference between one-time activations and rentals for SMS verification?<\/strong><\/p>\n<p>A: One-time activations are designed for a single OTP and quick verification. Rentals are better when you expect future logins, re-verifications, or recovery messages.<\/p>\n<p><strong>Q4: What should I not use temporary numbers for?<\/strong><\/p>\n<p>A: Don&#8217;t use them to violate platform rules, evade restrictions, or automate abuse. Use them for legitimate privacy and testing needs.<\/p>\n<p><strong>Q5: Why is my ProtonMail 2FA code invalid even though I typed it right?<\/strong><\/p>\n<p>A: Time sync issues are a common cause. Turn on automatic date\/time on both devices, then try again with the current code.<\/p>\n<p><strong>Q6: What if verification emails aren&#8217;t arriving?<\/strong><\/p>\n<p>A: Check spam\/junk folders, search for the sender name, confirm the address you entered, and resend once after a short wait. If nothing arrives, use another verification method if available.<\/p>\n<p><strong>Q7: Is it safe to enter OTP codes on public Wi-Fi?<\/strong><\/p>\n<p>A: It can be risky. Avoid unknown networks when possible, don&#8217;t share your codes, and enable stronger account security like 2FA once you&#8217;re in.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><strong><b>Conclusion<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you&#8217;re seeing invalid code, don&#8217;t brute-force it.
