feat(auth): normalize emails to lower case - #333
Merged
Conversation
Mail hosts treat addresses case-insensitively, but the app sent them verbatim, so an account registered as "Max@Web.DE" failed to sign in as "max@web.de". Fold email fields as the user types via EmailInputTransformation, so the field shows what will be sent, and pair it with KeyboardCapitalization.None so the keyboard stops fighting it. The transformation replaces per character rather than lower-casing the whole buffer, keeping length and cursor stable. Text that never passes through the field — prefilled values, autofill — needs the same treatment, so every read that reaches EmailValidator or the network goes through normalizeEmail(), which also absorbs the trim() calls it replaces. Covers login, register, forgot password, re-auth, change email and guest upgrade.
