OpenAI's personal Agent product Dot has introduced new features: it can read login verification codes in connected mailboxes, complete logins on behalf of users, and support one-time or continuous authorization. It will later integrate with password management tools. Currently, multiple tech vendors are advancing the implementation of personal Agent login capabilities, but each has different considerations regarding authorization boundaries and privacy protection. At present, only email-based verification codes can be handled, while complex graphics, SMS, and other verification methods still require user intervention, and the experience is not yet stable. Verification codes are only one of the bottlenecks in implementing personal Agents. The industry is focusing on improving the speed and smoothness of AI computer operation and promoting its ability to independently complete entire task sets, covering both daily and work scenarios. However, this field has already shown signs of insufficient momentum, with user activity declining significantly over time, and how to convert early-adopter users into sustained users remains a core unresolved issue. The progress in automatically filling verification codes has brought personal Agents one step closer to independently completing real tasks.
