In this talk, we’ll dive into the secu­ri­ty pit­falls of token-based authen­ti­ca­tion, focus­ing on JSON Web Tokens (JWTs). From com­mon attack vec­tors to spe­cif­ic vul­ner­a­bil­i­ties, such as token theft from inse­cure stor­age loca­tions like local­Stor­age, we’ll explore how improp­er han­dling can turn tokens into secu­ri­ty lia­bil­i­ties. Through live demos, you’ll see real-world exam­ples of attacks like token hijack­ing, and we’ll dis­cuss prac­ti­cal defense strate­gies to secure tokens effec­tive­ly. Gain insights to for­ti­fy your appli­ca­tions and ensure that tokens remain safe inside your authen­ti­ca­tion architecture.
