Hi there. I know HSBC can be tricky, and has been for years, but thought I'd point out an issue that might be fixable.
Browser: Safari Version 11.1.2 (11605.3.8.1)
OS: El Cap 10.11.6 (15G22010)
I have one login setup for HSBC in 1P. HSBC has a two page login process. First page is USERNAME only, and is filled correctly by 1P. 2nd page is DOB using 3 fields, one for month, 2nd for day and 3rd for year, followed by a PASSWORD field.
On page two there appears to be no way to get 1P to autofill the DOB. Instead it forces the USERNAME into the YEAR field and then correctly fills the PASSWORD.
I use to have to Login cards for pg1 and pg2, but even this wouldn't solve the problem, as there appears to be no way to fill the 3 DOB fields.
