In a recent post, Paytm’s Founder and CEO, Vijay Shekhar Sharma, delved into the critical aspect of password strength and the time it takes for hackers to crack them. Sharma emphasized that the length of a password is the most crucial factor in online security and provided an illustrative chart to support his argument.
Sharma shared this insightful information on X, formerly known as Twitter, accompanied by a note that stated, “It is the length of the password that matters most. Add a few small caps alphabets too to make one.”
The chart Sharma posted breaks down the time it takes for hackers to crack passwords based on various criteria:
- Number-Only Passwords: Hacker cracking times can vary from “instantly to six days,” depending on the characters used.
- Lowercase Letters: For passwords consisting of lowercase letters, hackers can instantly crack those with lengths between four and eight characters. A four-character password, for instance, can be cracked instantly.
- Complex Passwords: For passwords that include a combination of numbers, uppercase and lowercase letters, the time taken to crack an 18-character password extends to an astonishing 2tn years. In the case of passwords with symbols included, the time extends to an even more staggering 26tn years.
Sharma’s post quickly gained traction on social media, igniting a flurry of inquiries and discussions. Users raised questions about the security of credit card and debit card PINs, which can be considered as passwords, as well as the limited options provided by most mobile apps, typically offering only four-digit PINs.
Furthermore, concerns were raised about the interval wait time between each password attempt, with one user highlighting the delay implemented by online sites to prevent DDoS attacks and the resulting extended time required to crack a password under such circumstances.
Despite these queries and concerns, many users expressed their gratitude to Vijay Shekhar Sharma for sharing this valuable information, highlighting the importance of online security and the need for strong, lengthy, and complex passwords in the digital age.
