Follow these steps at your club’s own website. Available screens and actions depend on your account’s role and the programs your club has enabled.
Overview
Members can sign in by text only after verifying their mobile number from inside the portal.
Set up text sign-in
Sign in with an email link or Google, open Membership → Household, go to Sign in by text, enter your number, and verify the code you receive. After that, you can choose text sign-in on the login page.
Text sign-in can't be set up on a shared computer. A member who signed in without ticking Keep me signed in on this device is told to sign in on their own device, with the box ticked, and try again. That is on purpose: a number added on a shared computer would keep working after that sign-in ends.
When a number is set up, the club emails the member's sign-in address to say so. The email names only the last four digits of the number. If the number replaced an older one, it names that one too. A member who gets this email and didn't set up text sign-in should turn it off on their Membership → Household page and use Sign out all other devices under Account → Security & devices.
A phone number on the household record is not enough to enable text sign-in. If a member has a new number, they should turn off text sign-in or ask staff to unlink the old number. Staff can unlink it only when the member's sign-in is used at your club alone; if they also sign in elsewhere on Swim Ops, the member turns text sign-in off from their portal. Codes expire quickly and repeated requests can be limited.
Only US (including Puerto Rico and the other US territories) and Canadian mobile numbers can receive codes. Numbers in other countries that share the +1 code, such as the Caribbean, are refused, and so are 900 numbers.
There are daily limits too. One account can ask for only a few set-up codes a day (and turning on text notices counts toward the same limit); a member who hits that limit is told to try again tomorrow. Typing a number that turns out to be linked to a different account counts toward that limit as well, so a member who mistyped a few times may have to wait until tomorrow.
One number can get about ten sign-in codes a day. Only codes that were actually texted count, so requests refused for coming too fast don't use any of them up. After the tenth, the login page still says a code was sent, but no text arrives until the next day. The page can't say more, because the same page has to answer the same way for a number Swim Ops has never seen. A member in that spot should sign in by email link or Google, which still work.
