Need★★★☆☆Feature request

当我的丈夫尝试登录他的Gmail账户时，系统要求我在手机上验证。我正在工作，无法做到这一点，而且他打电话给我提供验证码时我并不总是在线。他想在我们家的电话或他的手机上接收电话，但这不是一个选项。如何添加第二个电话号码用于验证？我们有两个电子邮件地址；为什么不能有两个号码或两种身份验证方式来登录？ Chinese research excerpt

Scoring summary

Evidence confidence = strength × evidence volume × source diversity × payment × competition × trend × 10. Counts use independent content items; only first-hand pain, current spend, explicit willingness to pay and concrete feature requests affect the score. Repeated posts by one author are discounted. Scoring and status changes follow deterministic rules.

“Evidence-backed” means the problem appears real, recurring and connected to spending. It does not mean the business is worth building. Read the full methodology.
