Short answer: it’s safest to clear the old cookies first so you don’t end up with a mixed state. Then set your new evz_user1, evz_user2, … cookies. Leave evz_user_no unset if you want the account picker to appear whenever there are 2+ accounts.

Here are copy-paste snippets:

1) Clear legacy cookies

(If you’re on http://localhost, remove ; Secure.)

// Clear primary + list + any previously set enumerated cookies you used
document.cookie = 'evz_user_no=; Max-Age=0; Path=/; SameSite=Strict; Secure';
document.cookie = 'evz_user_nos=; Max-Age=0; Path=/; SameSite=Lax; Secure';

// If you had older names, clear them too (optional)
document.cookie = 'evz_user_no_2=; Max-Age=0; Path=/; SameSite=Strict; Secure';
document.cookie = 'evz_user_no_3=; Max-Age=0; Path=/; SameSite=Strict; Secure';

// Clear any previous enumerated format if you used it already
document.cookie = 'evz_user1=; Max-Age=0; Path=/; SameSite=Strict; Secure';
document.cookie = 'evz_user2=; Max-Age=0; Path=/; SameSite=Strict; Secure';

2) Set the new enumerated cookies

// 7 days = 604800 seconds  (remove "; Secure" on http)
document.cookie = 'evz_user1=U-000123; Max-Age=604800; Path=/; SameSite=Strict; Secure';
document.cookie = 'evz_user2=U-000789; Max-Age=604800; Path=/; SameSite=Strict; Secure';

That’s it.

• With one evz_userX, the SDK will auto-use it.

• With 2+ evz_userX, the Account Picker will show.

• If you ever want to force a default without showing the picker, also set:

  document.cookie = 'evz_user_no=U-000123; Max-Age=604800; Path=/; SameSite=Strict; Secure';

  (Our hook still shows the picker when there are 2+ accounts, but it’s fine to leave evz_user_no unset to keep behavior obvious.)
