Rule
| Item | Condition | Shown on screen |
|---|---|---|
| Length | At least 8 characters | 「8文字以上」 |
| Letter | At least one half-width A–Z or a–z | 「英字を1文字以上」 |
| Digit | At least one half-width 0–9 | 「数字を1文字以上」 |
How characters are counted
Full-width letters and digits do not count as letters or digits. Length is counted one character at a time, and a full-width character counts as one.
When the rule is checked
The rule is checked when an account is created. It is not checked when you sign in. Clicking 「アカウントを作成」 with a password that does not meet the rule shows 「パスワードが要件を満たしていません」.
What the screen shows
On the account creation screen, three items are shown below the password field, and each changes colour once it is met.
